Skier Triggered Avalanche; Sluice, Tuckerman Ravine – March 4, 2022

On the morning of March 4, 2022 around 11:30am a skier triggered an avalanche while skiing Sluice in Tuckerman Ravine. They were caught, carried about 300 feet, not buried, and uninjured, coming to rest on top of the debris pile above “Lunch Rocks.”

Near Misses in the Gulf of Slides

On a tour to the Gulf of Slides via the Graham Trail, two snow rangers observed the aftermath of a D2-sized avalanche in Main Gully. While discussing the nature of the avalanche and observing the rapid and intense snow loading from northwest winds, a second D2-sized avalanche occurred in Main Gully. Debris from these two avalanches was 8-12 feet deep. No one was caught or injured in either of these avalanches, however, six people in three unique teams of two had been traveling at the bottom of Main Gully within 20-30 minutes of both avalanches.

Human Triggered Avalanche in Left Gully, Tuckerman Ravine

On December 5 at approximately 12:00 pm a skier triggered a shallow soft slab avalanche near the top of Left Gully. The skier was caught and carried, and a short distance later triggered a 2nd, larger avalanche. The skier was carried 800 vertical feet, unharmed and landed on top of the snow at the mouth of the gully.

Avalanche Fatality, Ammonoosuc Ravine

Wednesday, February 3, 2021, a NH Fish and Game officer contacted the lead snow ranger at the USFS Mount Washington Avalanche Center to ask for assistance in locating the vehicle of an individual who was reported missing on Tuesday night, Ian Forgays, a 54 year old male from Vermont. Recent communications between Ian and his friends suggested that he had been planning a day of backcountry skiing, either in Ammonoosuc Ravine or Monroe Brook on the west side of Mount Washington, on Monday, Feb. 1, prior to the start of a significant winter storm arriving Monday night and continuing Tuesday.

Human-triggered avalanche in Left Gully

Events:

On January 22 at 3:20 pm, a skier was caught by an avalanche triggered by his party and carried from near the top of Left Gully almost to the floor of the ravine. A ~six inch slab of new and wind deposited snow released from the uppermost start zone from skier 2’s feet as skier 1 made their first turn. Skier 1 was quickly swept into and under the moving debris and lost their skis and poles. When the flow stopped, they found themselves buried face down, fortunately with their head very near the surface, but the rest of their body buried by two feet or more of debris. They were unable to move but could raise their head for a breath.

Skier 2 did not see their friend and skied away. (Edit: Skier 2 found their friend but, without a shovel, was unable to dig them out.) Ultimately, skier 2 alerted others down by the Connection rescue cache. Bystanders closer to the scene began to dig out skier 1. Others arrived, including Hermit Lake and Harvard Cabin caretakers and later, snow rangers, to assist.

Analysis:

Just prior to the avalanche, a snow ranger suggested to the two skiers, who did not have beacons, shovels or probes, that they ski the lower angled slope between Right Gully and LC or the lower section of Left, if they skied anything at all. They later told snow rangers that the excitement of new snow drove them to the top and into the upper start zone where the incident then unfolded. These two were very helpful to the community by honestly sharing their story with snow rangers.

There were no natural avalanches reported that day which carried a Moderate danger rating, though the forecast included possible human triggering of D1-2 wind slabs. This pair was among many poorly equipped skiers or skiers traveling alone. Low visibility marked conditions for the day with periods of moderate snow squalls and minor wind loading at the tops of gullies.

Reading the forecast carefully, applying safe travel techniques, and carrying the proper equipment are fundamental to recreating in avalanche terrain. It is critical to acknowledge that the majority if avalanche incidents and fatalities occur in Moderate danger rating days where the avalanche hazard may include the potential for isolated, stubborn but large avalanches OR widespread, smaller avalanches, such as this day. Both can carry real consequences.

Editors note: Skier one’s skis were found later and returned by a good samaritan. Also, Skier One reported that his GPS watch recorded a total vertical drop during the avalanche of 850′ and a max speed of 53 mph. 

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.

NHPR at Hermit Lake

We had the privilege of spending the day with Sean Hurley from NHPR a couple weeks back. Here are the results of tour of the east side in in pictures and audio. Once again, Lily proves herself to be the most popular and interesting snow ranger while Sean demonstrates one of the most soothing and mellow voices on the radio today. 😉
