Sliding fall, Chute, 2019-5-12

Sliding fall, exit of Right Gully

Close call: Fall into deep waterfall hole

As winter turns rapidly to spring, a number of hazards become prevalent in the steep terrain of the Presidential Range and particularly the Headwall of Tuckerman Ravine. Waterfall holes, glide cracks or crevasses, moats around cliffs and rocks, and other deep holes open as the thick snowpack melts. A fall into these holes, which often also have significant amounts of cold flowing water which can quickly cause hypothermia, can be very difficult to escape or be rescued from. Such accidents have resulted in several fatalities in Tuckerman Ravine. A lucky skier had a very close call in this type of accident yesterday.

At 1:58 PM on Monday, April 22, a skier fell over the Tuckerman Ravine headwall and into one of several waterfall holes. Partners and bystanders quickly initiated rescue efforts and also called 911 for emergency response. Unsure of where under the snow the fallen skier was, a beacon search was initiated and could have been helpful, though this was a non-avalanche accident. At 2:18 pm, after 20 minutes out of view to the rescuers, the subject climbed out of a different hole in the snow and slid down to the rescue party below him in the slope. He had lost his skis, poles, and pack.

The subject was alert, oriented, and able to walk but in pain from several impacts during the fall. He was also cold and wet from spending most of the 20 minutes in very cold flowing water, though not submerged. The rescue party quickly changed his clothes to drier ones. They wrapped him in a sleeping bag and briefly transported him in a rescue litter obtained from the nearby Connection Cache of emergency supplies. In effort to warm the subject, the rescue party then helped the subject begin walking down the Tuckerman Ravine Trail towards Hermit Lake.

The fall line glissade track just right of center leads up to waterfall hole and accident site, with partners of the subject shown helping him walk downhill.

Meanwhile, U.S. Forest Service Snow Rangers were notified of the incident by emergency dispatchers. They travelled to Hermit Lake with urgency, aware than similar accidents have historically been fatal. Upon arriving at Hermit Lake, Snow Rangers were told by the AMC caretaker that the subject had extracted himself from the waterfall hole and was walking, with aid, down to Hermit Lake. They proceeded up the trail, meeting the rescue party at 3:20 PM. The subject, still alert and oriented but now warmer, was transported to Pinkham Notch via snowcat and released to the care of friends.

This positive outcome should be regarded as quite lucky and be taken as a warning for all who travel on steep snow slopes in spring conditions in our mountains. Had the subject, who was a strong athlete and also a climber, been unable to self-extricate himself from the waterfall hole the outcome could have been far worse. Many of these deep holes in the snow are impossible for even the strongest individual to climb out of. Extricating a person from these holes can be very dangerous for rescuers and is difficult to accomplish in a sufficiently timely manner to save a life. We know the subject would urge you to learn from this accident, giving potentially deep holes and glide cracks in the snow a wide berth and taking care to not fall above one.

The rescue initiated by partners and bystanders of the subject was a positive example we would also like you to learn from. Partners were paying attention to each other and able to quickly initiate a rescue. They had sufficient dry clothing and emergency supplies to provide proper care for the subject. Several emergency medical professionals observed the accident and immediately helped rescue efforts. Rescuers had knowledge that a litter and hypothermia wrap materials were available in nearby Connection Cache and used them. All individuals on the scene had avalanche rescue gear, as large wet slab avalanches were forecast as unlikely but not impossible that day. While a call was made for professional rescue, this group realized that they could provide timely aid to the subject and took appropriate action that could have resulted in an effective evacuation had professional rescue been delayed or unavailable. This self-reliant level of accident response is commendable. It is also the level of response that everyone travelling in the backcountry should be prepared for, every time you’re out.

Please learn from this accident to have a safer spring ski season, and see you on the hill!

April 11, 2019 Avalanche Fatality, Raymond Cataract

Around lunchtime on Thursday, April 11, 2019, two hikers took a break on the summit of Lion Head. This ridge separates Tuckerman Ravine from a stream drainage to the north known as Raymond Cataract. While on Lion Head, they noted a skier descending into Raymond Cataract, an ephemeral, but recently popular ski descent only possible during winters with a deep snowpack.

The hikers remarked on the solid and skillful turns the skier was making and watched him descend out of view. At the same time, two skiers skinning up the Tuckerman Ravine Trail watched a solo skier make a couple of turns in upper Raymond Cataract and then returned their focus to skinning. Unknown to anyone, within a few turns of both sightings, Nicholas Benedix would ski over a convex 39 degree bulge and trigger a fatal avalanche.

Search for Missing Hiker

On Sunday March 17, Snow Ranger staff from the Mount Washington Avalanche Center participated in a search for a missing hiker. Agencies involved included the NH Fish & Game, Mountain Rescue Service and  Androscoggin Valley Search and Rescue.  Teams searched areas of “last known location”. The search was discontinued at the day’s end pending additional information.

On Sunday, February 10, 2019 at 4:45 p.m. U.S. Forest Service Snow Rangers from the Mount Washington Avalanche Center responded to a report of an overdue climber. Local volunteer search and rescue teams assembled with Snow Rangers to search the terrain above Huntington Ravine and below the climbers intended route.  The climber was attempting to climb a moderately difficult snow and ice climb called Central Gully. Icy surface conditions that developed in the mountains following several days of warm temperatures and rain increased the danger of long sliding falls the day of the accident. The body was found at approximately 7:45 p.m., recovered from the mountain, and released to local authorities that night. The incident is currently under investigation with law enforcement. When it is appropriate to do so, the Mount Washington Avalanche Center will release an incident report as a public safety and educational tool designed to inform the recreating public of any lessons learned.

The U.S. Forest Service operates the Mount Washington Avalanche Center (MWAC). MWAC issues daily avalanche forecasts and assumes search and rescue responsibilities from the State of New Hampshire for the Cutler River Drainage annually between December 1st and May 31st. In addition to identifying probability of encountering snow avalanches, the forecast contains mountain safety information to help guide Forest visitor decision-making when entering the backcountry.

Human Triggered Avalanches

On April 7, 2018, seven avalanches occured in Tuckerman Ravine. All were human triggered. This write-up discusses the weather and snowpack that lead up to these events, an objective summary of the events, and an analysis of factors that lead to at least five people being caught in one of the avalanches.

Weather

In the week leading up to April 7, 2018, our snowpack saw two rain events. The first was March 29 and 30 which delivered 0.75” of rain followed by 0.32” of rain on April 4. Both of these rain events were followed by hard freezes. On Friday, April 6, light snow showers began just after noon and continued through sunrise the following day. By the time snowfall stopped, the snowplot at Hermit Lake recorded 16cm (6.3”) of 9% snow while the summit recorded between 7 and 8” (this is an estimate based on hourly observations as the total snowfall was recorded as less due to excessive blowing snow) of snow. When snowfall began on Friday, wind at the summit was around 30mph from the south. Overnight, wind direction shifted to the west and speeds increased to 60-70mph. Weather on Saturday April 7 was clearing skies, winds diminishing to around 40mph from the west, and temperatures in the single digits on the summit and reaching into the 20sF at Hermit Lake. This weather pattern built a robust melt-freeze crust over which wind slab was built from new snow and wind April 6-7. This touchy wind slab was the avalanche problem involved in all known avalanches on April 7.

Summary of Events

During the morning of April 7, three avalanches were intentionally triggered by skiers. All three were ski cuts, two occurring in Lobster Claw (both SS-ASc-R1-D1.5-I) and one occurring on the rollover of the Little Headwall (SS-ASc-R1-D1-I). Slab depths were up to 14” and all occured on a layer of softer snow immediately above the melt-freeze crust. Of note in the Little Headwall was that the second skier through was able to trigger the “hangfire”, or slab remaining above the crown of the initial avalanche.

We have less definitive information on the Left Gully and Chute avalanches, which occurred shortly before and after the Hillman’s Highway avalanches, respectively. We believe that no one was caught or carried by either avalanche, both of which were triggered unintentionally. Left Gully, which was rated Moderate, produced an avalanche from a relatively thick though isolated pocket, while Chute, which was rated Considerable, produced a larger in area avalanche from a thinner slab. Both are estimated SS-ASu-R2-D1.

Unlike the other avalanches this day, the avalanches in Hillman’s Highway did involve a number of people being caught and carried. At approximately 2:00 pm, at least 40 people were climbing and skiing in Hillman’s. An individual climbing uphill from the looker’s right fork to the looker’s left fork triggered the initial avalanche as they entered the looker’s left fork. This person was not carried in the slide. The crown of this avalanche was approximately 300’ below the top of Hillman’s and ran ⅔ of the way down (SS-AFu-R2-D2-I). Of the many people in the avalanche path, at least 5 were caught and carried. USFS Snow Rangers responded to the incident and identified one injured skier who was ultimately transported to Pinkham Notch with a back injury that was not life threatening. Another individual who was also caught and carried sustained a minor injury to their hand.

The second avalanche was triggered around 2:30pm, within minutes of the initial Snow Ranger team arriving on scene. The trigger was unknown at the time, but consensus of bystanders is that this second avalanche was triggered by the same individual who triggered the first, having topped out on the ridge and beginning to ski the hang fire slab above the initial crown. This second avalanche was smaller (SS-ASu-R2-D1-I) and luckily did not capture any people or result in injuries.

Analysis

Many opportunities for learning are presented by this day which which fortunately did not involve more serious injuries. First, it’s an excellent reminder that avalanche conditions can develop during the spring months which bring crowds of backcountry skiers to Tuckerman Ravine. As with any time of year, these avalanches can widely vary in size and character. Avalanches can be of minimal concern on certain spring days, but April 7 was a day with avalanches as the primary concern for alpine travelers. On any such day, anyone venturing into avalanche terrain should bring a beacon, shovel, probe, and knowledge to use them effectively.

Carrying avalanche rescue gear is a cardinal rule for travelling in avalanche terrain. Another is travelling one at a time through areas exposed to avalanche danger. This requires recognizing avalanche terrain, which includes both terrain capable of producing an avalanche and terrain threatened by avalanches. A phrase often heard in the courtyard is, “It’s just Hillman’s”. All of Hillman’s Highway is avalanche terrain. On top of that, it’s easily the biggest gully in Tuckerman Ravine and is particularly confined. Exposing one person at a time to avalanche danger is crucial, particularly on a day like April 7. It’s likely that nobody would have been injured had this been the case.

Avalanche danger was Moderate in Hillman’s Highway on this day, which forecasts natural avalanches as unlikely and human triggered avalanches as possible. These possible human triggered avalanches can be either small and in many areas or large and in specific areas. With a number of similar avalanches in other Moderate rated areas, we consider April 7 as a small avalanches in many areas kind of day. It’s worth noting that a Moderate rated day for large avalanches in specific areas is sometimes referred to as “scary moderate”, in which you’re less likely to find signs of instability but potentially able to trigger a large avalanche. Further, remember that even small avalanches can ultimately be fatal.

The Chute was rated Considerable and produced a slightly larger in area avalanche from a thinner slab. The primary distinction between Moderate and Considerable is increased likelihood of both natural and human triggered avalanches with greater chance for larger avalanches. Other Considerable areas received little if any traffic, which we suspect is a reason that more did not produce avalanches.

All avalanche problems exhibit some degree of spatial variability. This means that the snowpack is not uniform across the terrain and avalanches can often only be triggered from specific locations. A number of people can travel on a slope, particularly one as large as Hillman’s, before someone finds this specific location and triggers an avalanche. Tracks on a slope do not mean it’s safe to ski or climb.

The Little Headwall was not rated on April 7 for lack of snow, but did have enough snow in one isolated pocket to produce an avalanche. Unrated terrain, which encompasses all of our terrain early and late in the season, can produce avalanches. The human triggered avalanche in Central Gully on Dec 1 of this season is another example. We do issue danger ratings for areas of most concern during the bulk of the season in Tuckerman and Huntington Ravines, but avalanche activity is not confined to areas forecast on a particular day.

Finally, we should touch on ski cutting. The avalanches in the Little Headwall and Lobster Claw were intentionally triggered in a controlled manner through ski cutting. This process of intentionally skiing a specific part of a slope likely to trigger an avalanche, with speed and from one safe zone to another, is an advanced practice and is only appropriate under certain conditions. A book could easily be written about the practice of ski cutting, but a simple explanation is that it is only wise when you possess a high degree of certainty about what the the ski cut will produce AND the consequences if you’re wrong. In particular, ski cutting is inappropriate when an avalanche may initiate above you. On April 7, we had the rare conditions for our terrain in which instability was limited to surface slabs and individuals were able to ski potential start zones for isolated and small pockets of wind slab. Certainty was high both in terms of anticipated result and consequences for being wrong, and avalanches above the individuals ski cutting were nearly impossible. Further, other people were not in the potential avalanche runout zones.

The human-triggered avalanches on April 7 did result in injury, but everyone on the mountain lived to ski and climb another day. Luck certainly contributed to this relatively positive outcome, as did the relatively small but widespread type of Considerable and Moderate avalanche danger that day. We who like to travel in avalanche terrain rarely get such valuable lessons without more serious outcomes. Great turns can be had with minimal risk on such days, but only by choosing terrain that matches your preparedness, knowledge, certainty, and skill level.

Human-triggered avalanches, Hillman’s Highway & Gulf of Slides

On Saturday, March 10, 2018, two separate avalanche incidents were reported. During the previous 2 days, 14.5″ of snow was deposited at Hermit Lake from a nor’easter and the upslope snowfall that followed. This storm was accompanied by moderate winds that rose to the 60’s mph the afternoon before. Saturday’s advisory called for 4.5″ more snow with increasing wind shifting slightly to the NW. Avalanche danger was rated Considerable in Hillman’s Highway, along with Left Gully and the Headwall forecast zones.

Around mid-day, a party of three talked with a snow ranger on duty who advised that low visibility and continued wind loading made their plan to travel into Hillman’s Highway unwise. The party hiked to Hillman’s and entered the 75′ wide couloir onto a 15-20 degree section of the otherwise steeper runout. Soon after the party returned to the courtyard and reported that everything the snow ranger had cautioned against had played out. Two were struck by debris, knocked down, and carried downslope. Fortunately, much of the energy of the debris flow was absorbed by boulders and holes from a warm spell which reduced our snowpack substantially. When the threat of natural avalanches occurring is elevated, the risks are as well. The natural avalanche that occurred in Hillman’s Highway was much larger and would likely have been unsurvivable.

The same day a party of two skiers set a skin track near the middle gully in the Fingers area of Gulf of Slides, in sparse trees. As the terrain steepened, they began to boot along the left edge of the gully next to the trees. The snow was loose and dry with “no shearing and bonding felt okay”. The first skier had been to this area many times and stayed out of the gully as they made their way towards the rollover near the top. They had spread themselves out as they moved up the slope but paused as they reached the rollover because “something felt wrong”. In moments, the slab failed a “couple hundred feet above” the party and hit both skiers. The first skier was carried but, being on the edge of the gully, he escaped the main flow of debris while the other skier clung to a nearby bush. The skier that was carried turned his beacon to search and could not locate a signal of his partner, who was still above him. Shortly after the caught and carried skier texted for help on his cell phone, the pair made contact and eventually were able to call off the rescue response. The skier who held onto the bush lost his poles while the skier who was carried lost all his equipment though eventually recovered one ski.

Later conversations with the skiers in Gulf of Slides revealed a debate as to whether or not they triggered the slope. They considered it likely that they did not trigger the slope, but rather that it had avalanched naturally. From our perspective, the trigger is relatively unimportant in this instance. If the avalanche had not released while ascending, it is possible that they could have made it to the top and triggered the slope on the way down. In that case, much more of the slab could have been above them with more serious consequences likely. After some reflection, looking at weather data and reading the avalanche advisory, the triggering skier admitted that “overconfidence due to personal experience” in that particular area led him to ignore the obvious red flags that existed due to the snow and weather conditions that day. After the period of warm weather and ice crust which had dominated recent ski conditions, it seems likely that the scarcity heuristic was in play as well. The call of fresh powder is hard to ignore sometimes but it is important to remember that good luck can play a role in good outcomes like this one and luck is one thing no one can count on.

Sliding fall in Hillman’s Highway

Icy conditions will always be a challenge despite the use of self-arrest poles. Once momentum is gained from a skiing fall or unchecked fall while climbing, it is doubtful that even a a well deployed ice axe would work on a knife hardness, icy and steep surface such as the conditions encountered in the report that we received. Here is the submission:

“sliding fall. after climbing 2/3 of the way up hillmans and not finding a ton of good snow we transitioned for our Icy decent. I was the the third and final member of my group to descend. There was a small ribbon of wind slab on the skis right side of the Slide, hand shears had shown positive results. My two partners side slipped the ice to a good point of safety. I tried the wind slab but after a few untrustworthy turns in it I bailed for the more predictable surface of ice. After coming to a stop I started skiing once more and on my second turn I went down. I have practice self arresting on snow with a whippet and skis on but not on ice. I tried twice to self arrest with no luck. I slid for about 200ft before managing to slow myself down in some soft snow that was piled on top of a rock. Unfortunately as i came to a stop my body turned and I fell of the side of the rock landing on my shoulder and dislocating it. My partners and I were able to get in to the pine tree area where we tired to reset the joint with no luck. We slung and secured my arm. I transitioned to crampons and self rescued with a fast stop at hojo to get an ice pack. I then boot packed pinkham then the hospital. A few things I noticed: even with practice my whippet was not an adequate self arresting device in the ice conditions and also my skis made it impossible to roll on to my stomach and execute a proper self arrest.”

 

Long Sliding Fall – Right Gully, Tuckerman Ravine

At about 1:00 PM, a climber took a long sliding fall while ascending Right Gully in Tuckerman Ravine. The subject lost their footing on very hard, icy snow and was unable to self-arrest with an ice axe. The fall occurred near the top of Right Gully and the resulting high speed slide was halted below the gully by exposed bushes and rocks. The fall totaled approximately 300 vertical feet. The subject was able to walk away from the accident, traveling on foot with help of their climbing partner down to Hermit Lake. The primary injury was presumed to be bruised or fractured ribs from impact with the bushes and rocks that stopped the fall. U.S. Forest Service Snow Rangers transported the subject via snowmobile from Hermit Lake to Pinkham Notch.

The subject and witnesses of this accident unanimously described the event as a close call, all surprised that the outcome was not more serious. The subject was indeed lucky to eventually slide into a generally bushy area as opposed to the many nearby rocks that would have likely resulted in greater injuries. Further, the subject was not wearing a helmet and was very fortunate to avoid hitting their head. The party had climbed Right Gully several times in past seasons and stated that they normally did wear helmets while travelling in steep alpine terrain. Further, they did have experience climbing steep snow and were otherwise properly equipped with mountaineering boots, crampons, and ice axes.

This accident highlights the risk of climbing on steep snow slopes when conditions are hard and icy, making self-arrest all but impossible. Such snow conditions can develop when steep slopes in Huntington and Tuckerman Ravines are snow covered. While firm conditions can inspire confidence for climbers travelling uphill with crampons, it can be incredible difficult to arrest a fall once sliding with any amount of speed. While strong self-arrest skills are crucial for travelers on steep snow slopes, it’s just as important to remember that you may not be able to self-arrest in hard snow. Close calls like this one should remind us to always consider the likelihood and consequences of a long sliding fall when travelling on steep snow. These incidents are common and can easily have more serious outcomes.

Sick Hiker, 5/11/17

A pair of hikers departed Pinkham Notch headed for the Mount Washington Summit at 9:00 AM. At 3:00 PM, USFS Snow Rangers were notified that the hikers had called 911 via their cell phone. One of the pair was reported to be vomiting and unable to hike, while the other had no reported issues. The pair accurately relayed their location, the Lion Head trail several hundred feet below its junction with the Tuckerman Ravine trail, at 5,600 feet in elevation. One Snow Ranger responded to the incident from the Summit, via auto road vehicle transport by Mount Washington State Park staff. One AMC Hermit Lake caretaker proceeded to the scene on foot from Hermit Lake. Both arrived at 5:00 PM, by which time the subject had ceased vomiting and presented fatigue as a chief complaint. Following the provision of food and water, the subject felt strong enough to proceed on foot to the Mountain Washington Summit for vehicle transport down the auto road.

Analysis: The party stated that they had received information on potential trails to the Mount Washington Summit from the AMC Pinkham Notch front desk staff. Through this information and their own judgment, they concluded that the Winter Lion Head route would be a reasonable ascent and descent option. The hikers did not have crampons, an ice axe, and mountaineering boots as we recommend for this route, but were able to ascend the steep mixed conditions of snow, ice, mud, and wet rock on the Winter Lion Head route. Given the timeline of their day, we can assume this was quite a challenging experience for the pair.

For the relatively warm conditions of the day, the party had sufficient clothing to keep warm. Their sneakers, cotton, and lack of an insulated puffy jacket would have greatly increased the potential consequences of the incident had the weather been more in keeping with the harsh conditions the mountain is famous for.

They brought relatively small amounts of food and water, though, and continued uphill until almost out of both. The subject of the incident appears to have been primarily a victim of the “bonk”, which is to simply deplete the body’s stored sugars faster than they are being replenished by eating. Further, the party left themselves with little food to fuel their descent. Inexperienced hikers are quite prone to this issue, overlooking the massive caloric demands of ascending and descending 4,000 feet on foot in challenging wintry conditions. The amount of food one eats in a relatively sedentary day can easily be half or less than the food needed when strenuously hiking for long durations. It’s important to remember that frequent food and water intake is equally crucial to maintaining physical strength though a full day. Think eating every hour rather than every few hours.

Maintaining the strength to move yourself through the mountains, and all the way back to the car, is absolutely crucial to avoiding incidents like this one. While the subject suffered no injuries, inclement weather combined with the not uncommon delay or lack of rescue response could have created a dire situation. While we’re always happy to help you to safety, never count on a rescue. Your body is the best means of transportation in remote environments, and proper fueling is crucial to maintaining this ability.

Stranded climbers

At around 11:30a.m., a pair of hikers set out from Pinkham Notch to summit via Huntington Ravine. At approximately 4:45p.m., snow ranger staff were contacted by AMC front desk staff that there were 2 hikers stranded near Central Gully in Huntington Ravine. Scouting in the Ravine revealed that the pair of climbers were actually located approximately 500′ below the top of the rim of Huntington between Damnation Buttress (5.6 WI3- M2-3; 700′) and Damnation Gully (WI3, 1,000′).  Two snow rangers climbed to the pair while one spotted from below. Two snow rangers and a Mount Washington Volunteer ski patroller approached the top via snow tractor on the Auto Road while 2 more ski patrollers served in dispatch and radio communications roles. The pair was reached at approximately 7pm by the climbing team and led to the top with assistance from the other two snow rangers from above. Rescuers and the pair reached the waiting Mount Washington Observatory snowcat at 10:02pm and returned to Pinkham Notch by midnight.

Analysis: The party reported that they had inquired at the AMC Front Desk about whether they could make it through Huntington Ravine to the summit without ropes and indicated that they were told that they could. The pair had limited climbing experience but managed to climb through 4th and low 5th class terrain unroped, with crampons and walking axes but without harnesses or other technical gear. Regardless of the source of the miscommunication with the front desk staff, it is important to thoroughly research an intended route, to re-evaluate plans based on time of day, climbing difficulty, along with prevailing weather conditions and experience level of the party. Fortunately, the pair were properly equipped with enough clothing, food and fluids. Though the summit temperature was around 10F that evening, relatively calm SE winds in 20 mph range made for a merely uncomfortable wait rather than a more serious outcome. It is interesting to note that a party of three found themselves stranded in the same position in similar conditions several years ago. It seems that the same line-of-least-resistance appears attractive to summit bound hikers confronted with the illusion that the Huntington Ravine trail or Central Gully are more difficult. While both of those routes are comparable in difficulty and have equally serious consequences in the event of a fall, the hardest climbing appears near the start of those two routes where a hiker could receive more immediate feedback on their route selection.

Icy Conditions in Tuckerman Ravine Lead to Two Evacuations

 

On Sunday, March 14, 2016, weather on Mount Washington was in the high 20’s (F) with bright sunshine and moderate northwest winds. Rain the previous week had saturated the snowpack which later refroze during the night when temperatures dropped to the mid-teens. By late morning, sun began to soften the snow, making for good skiing and snow climbing conditions in areas facing the sun. Unusually warm and dry conditions have predominated this winter, leaving many boulders and ice cliffs exposed which are usually buried by many feet of snow and avalanche debris at this time of year.

 

At approximately 3:00 p.m., a party of six skiers descended a 2,000-foot long 30-40 degree snow gully named Hillman’s Highway in Tuckerman Ravine. One of the six expert skiers slipped and fell part of the way down. Due to the icy nature of the slope, he was unable to arrest his fall which took him 700 -900’ down the slope over patches of ice, boulders, and at least one low angle ice and rock buttress. U.S. Forest Service Avalanche Center staff, Mount Washington Volunteer Ski Patrollers, an AMC Caretaker and several guides working in the area responded to render first aid and evacuate the patient. The crew performed a series of roped litter lowers to bring the man the remaining distance down the steep slope. Due the nature of the man’s injuries and calm weather conditions, a DHART helicopter was used to medivac the patient.

At approximately 5:30 p.m., Gorham Police Dispatch called U.S. Forest Service Snow Rangers to report a request for help for an injured climber near the summit of Washington on the Tuckerman Ravine trail. A rescue team was again dispatched to locate the party. Simultaneously, a team of NH Fish and Game officers, Mountain Rescue Service members, and NH State Park personnel used the Mount Washington Auto Road to approach the east snowfields in attempt to locate and evacuate the patient before dark. Given the nature of the injuries and time of day, DHART was once again to fly out the patient.  The patient was located at about 6:45 p.m. Due to flight regulations, the first DHART flight crew returned to base before the small rescue team could move the patient through difficult terrain to the landing zone. A fresh DHART crew arrived at the landing zone and the patient was transferred to Dartmouth-Hitchcock Hospital just before 10:00 p.m.

 

It is critical for people climbing and skiing on Mount Washington to understand the variability of surface conditions, particularly this time of year. This winter has brought several heavy rain events which have melted and saturated the meager snowpack. Due to this melting and refreezing action, many late spring hazards have already emerged, including undermined snow, deep holes in the snow from waterfalls, and as was the case on Sunday, an icy snowpack capable of creating long, sliding falls. These hazards add complexity to the already severe weather and associated avalanche dangers, which threaten the Ravines every winter.

Two long sliding falls on a frozen spring snowpack

On Sunday afternoon, March 13, two separate accidents occurred on the east side of Mount Washington. Both accidents involved long sliding falls and resulted in life-threatening injuries. Luckily, the skies were clear and the wind was calm, allowing both patients to be evacuated via helicopter.  There are several lessons to take away from these incidents, all coming back to the basics of being prepared and making safe travel decisions.

The first accident occurred when a skier slipped and fell in Hillman’s Highway.  Hitting several rocks on the way down, he sustained serious injuries requiring immediate evacuation.  Just as the helicopter departed Hermit Lake, the second call came in of an injured hiker on the summit cone.  Again, due to a serious injury and a lengthy carry-out, USFS Snow Rangers decided to use a helicopter for transport.  A large thank you must be given to all rescuers involved including the Mount Washington Volunteer Ski Patrol, AMC, Mount Rescue Service, AVSAR, NH Fish and Game, and several volunteers as the evacuations went smoothly and patients arrived at advanced care in a timely manner.

Weather and Snowpack Analysis

The week leading up to these two incidents coincided with the transition from winter to spring in Tuckerman and Huntington Ravine. On Tuesday, March 8 at 10pm, the temperature on the summit rose and remained above freezing for 48 hours.  During this time period, the summit recorded over 1.25” of rain.  After the warm up, temperatures dropped over 24 hours to the low teens, allowing the water-saturated snowpack to freeze solid.  On Saturday, temperatures warmed along with clear skies, allowing the snow to soften and turn to corn in many areas.  Skiers reported excellent spring conditions in The Lip, Right Gully, and the East Snowfields on the summit.  Left Gully and Hillman’s Highway had parts that softened, while parts remained frozen solid.  Saturday was followed by a blustery, clear day on Sunday.  Skiers reported certain areas softening up, however not to the degree as the day before.  Sunday was the type of day where as soon as snow had shadows cast upon it, the surface froze instantly into firm concrete.

Incident #1: Skier Fall in Hillman’s Highway

Around 3:20pm, six experienced skiers began to descend Hillman’s Highway. One of the skiers slipped and fell approximately 1,000 feet.  Upon arrival at the scene, USFS Snow Rangers and members of the Mount Washington Volunteer Ski Patrol determined the patient had sustained multiple life-threatening injuries.  After a lower down the remainder of Hillman’s Highway and transport to the awaiting helicopter at Hermit Lake, the patient was in the air and on his way to advanced medical care at 5:14pm.

The party of six initially started as multiple parties. The group that the patient was a part of toured into the Gulf of Slides and experienced decent corn conditions in Gully #1.  After the descent, the group decided to climb up and over Boott Spur and ski the looker’s right fork of Hillman’s Highway.  Standing at the top of Hillman’s Highway, the group, now joined by three other skiers, recognized the snow had changed dramatically from their previous run.  Two skiers, including the soon to be patient, donned crampons and an ice axe and climbed down about 200 feet to better assess and avoid the ice at the rollover.  Recognizing the hazard, members of the group collectively decided the risk was manageable with conservative skiing techniques.  The first skier made his way to the bottom of the choke and pulled aside to allow the second skier to go.  This second skier lost his edge on a patch of ice in the narrows.  As the snow had gone into the shade and turned to concrete, the skier had no chance to self-arrest and began an out-of-control slide down Hillman’s Highway.  Due to the low snowpack this winter, Hillman’s Highway, normally a good choice for novice Tuckerman skiers, was full of ice bulges and rock outcroppings.

Falling about 1,000 feet, he came to rest just above the dogleg near the bottom of Hillman’s Highway. The rest of the group made their way to him as quick as the conditions would allow.  Upon arrival, they prevented him from sliding further down the slope and immediately for help.  Snow Rangers, along with Mount Washington Volunteer Ski Patrol members arrived at the patient about 30 minutes after his fall.  The initial assessment indicated life threatening injuries.  Oxygen was administered, the decision to transport via helicopter was made, and the patient was strapped into a litter for travel to the awaiting helicopter at Hermit Lake.

Incident #2: Hiker Fall near South East Snowfields

At 5:16pm on Sunday evening, the Gorham Police Department received a call from hikers in distress on the summit cone of Mount Washington. There was confusion as to the exact location of the hikers, but they told Snow Rangers via cell phone that one member of their group of three had broken his femur during a glissade that turned into an out-of-control slide, and was now getting very cold.  A hasty team of one Snow Ranger and the AMC caretaker departed Hermit Lake at 5:45pm, ascending the Lion Head summer trail.  With weather still clear and calm, and dealing again with a possible life-threatening injury, Snow Rangers again decided the best evacuation option was with a helicopter.  The hasty team made visual contact with the hikers just before reaching the Alpine Garden/ Lion Head Junction.  At 7:07pm, the helicopter landed .25 miles away from the patient.  Snow Rangers quickly realized that due to difficult terrain, it was unfeasible to drag the patient to the LZ without a litter.  As the helicopter had to return to base at 8pm due to flight regulations, it left the scene at 7:40pm without the patient.

Over the next hour, more rescuers and a litter arrived. Upon further discussion with dispatch, a new crew boarded the helicopter and took flight, aiming for the landing zone established east of the Alpine Garden Trail.  This helicopter landed at 9:14pm, 10 minutes after the rescuers and patient arrived.  The helicopter departed with the patient at 9:26pm and rescuers made their way to the snowcat at the Cow Pasture and descended the auto road.

Analysis

Both of these accidents have the same mechanism of injury: long sliding falls on a frozen spring snowpack. However, in each case, the events that led up to the accident are different and worth investigating.  Finally, the treatment provided to each patient before rescuers arrived should be examined.

Spring skiing is all about timing. Start your day too early and the snow will still be frozen; end your day too late and your slope might turn to cement as you watch.  A knowledgeable Tuckerman spring skier will follow the sun, often starting the day on east or north-east facing slopes and slowly work their way across the Bowl and end the day on south facing slopes that are catching the last of the sun’s rays before the sun disappears over the Bigelow Lawn.  Catch a slope at its softest and there are times when if you fall, you won’t go anywhere as you sink into the corn or mushy mashed potatoes.  Once that slope goes into the shade, it can freeze almost instantly, necessitating the use of crampons on the way up and creating no-fall territory on the way down.

When the group of six skiers stood at the top of Hillman’s Highway, they discussed what conditions they would encounter. They realized the snow would be firm and very challenging to ski down.  Committing to the descent is understandable and I would hazard a guess that many others would have done the same despite the high consequences of a fall in these conditions.  Having toured from the Gulf of Slides, they had no mental map of where the ice bulges were and which way around the rocks were the best.  Skiing a run while it is frozen solid can be extremely challenging.  It is best to stack the odds in your favor and perhaps realize that there are one or two spots, while skiable earlier in the day when it was soft, that may require switching from skis to crampons for a few feet on the way down.

It is interesting to note that as this group of six skiers stood at the top of Hillman’s, a group of three topped out at the same spot after having climbed the gully. This group of climbers consisted of one person wearing crampons and carrying a mountaineering axe and two wearing snowshoes and carrying one technical ice climbing tool.  Seeing that two people had just snowshoed up Hillman’s further convinced the skiers the risk was manageable.  At least one skier later admitted the snowshoers looked terrified at what they had just done and perhaps this should have given the skiers pause for concern.

These three climbers continued to the summit of Mount Washington and eventually became the group of hikers who required the second rescue. This group pushed themselves hard and put in a long day, eventually making the decision to glissade down unfamiliar terrain rather than sty on the trail.  Had they reevaluated their plan of summiting as the day progressed and became late, they may have turned around and descended while still having energy.  It also must be taken into account that this group used inappropriate gear for the terrain.  Even with the traction provided by modern snowshoes, it is a miracle they were able to ascend Hillman’s Highway in the condition they found it.  Getting down any trail or terrain feature on the mountain that day with snowshoes would have been an extreme affair.

The final point worth discussing is the level of care provided by members of both groups to the patients before rescuers arrived. Of the six skiers in Hillman’s, only one of this group had training in first aid that he had taken several years ago.  When Snow Rangers arrived at the scene, 30 minutes after the fall, no care had been provided besides preventing the patient from sliding further down the slope.  If this accident had taken place outside of Tuckerman Ravine and help had not been .25 miles away, the result would have been drastically different.  On the summit cone, the first rescuers reached the scene over two hours after the incident occurred and the broken leg was still not stabilized.  The patient was half on the snow and the two uninjured were becoming cold from standing still and waiting for help.

The trend in backcountry enthusiasts taking avalanche education classes is rising. This is great to see.  Realize that a lot can happen while recreating in the mountains and there are skills you and your partner should learn before taking avalanche classes.  Taking first aid skills into the woods with you is a valuable insurance policy, as is learning what you can do with the contents of your pack.  Many schools around the country offer classes in wilderness first aid skills.  It was lucky these two incidents occurred close to help as they may have had different outcomes had rescuers not been close by.

There are plenty of lessons to take away from these two events, most stemming from the basics: being prepared and making safe-travel decisions. Preparedness with the right gear is vitally important.  This can get you safely home and also saves much time and energy as it means more efficient travel.  Preparedness with the right skills is necessary.  Ninety-nine times out of one hundred, the day’s adventure goes fine and everyone has fun.  However, that one time where something goes wrong, having the right knowledge available can mean a big difference to your partner or yourself.  History has proven that many accidents take place when people are tired and looking for a shortcut.  If it means getting home safe, taking the long way down may be the right choice.   Whether it’s following the lower-angled ridge that avoids the steep slope or shouldering your skis and climbing down a ski run, it may not be glorious at the moment, but your family and friends will praise you when you walk in the door at the end of the night.
