A General Bulletin is in effect for Tuckerman Ravine. A new General Bulletin will be issued within 72 hours or when conditions warrant. We are no longer monitoring conditions in Huntington Ravine.
Rain has been slower to materialize than expected for Sunday, but is expected to pick up through the day with some thunderstorm potential in the afternoon. Being below treeline during periods of thunder is always a good plan. If you are thinking of hiking above treeline, realize there are no options to hike through Tuckerman, only into it, and then backtracking down again. Obviously, if you get above treeline through a variety of other options there is also no way down through Tuckerman. Expect water ice to exist on many of the area’s higher elevation trails. This is particularly true on those just below the alpine zone where tree coverage has shaded them from the sun. Microspikes continue to be a smart thing to have with you if you explore trails with limited condition reports.
Skiing and riding lines are slowly becoming more limited, but they still exist. Left gully continues to be the longest line with the Chute being the steepest, though it has a poor run out with bushes and rocks. Because the ice has cleared high in the Sluice, a ski run to the down to Icefall/Lunch Rocks is an option, but as you reach the bottom portions the icefall threat from the Center bowl increases. Very large icefall occurred in this area on Saturday, which had two people literally running for their lives. Stay alert as we are still in icefall season. The Center Bowl and under the Lip looks pretty ugly and their icefall and open hole hazards are generally obvious. It may not be as obvious if in the fog with rain so planning to stay clear of these areas is a smart idea.
Spring Hazards in Tuckerman Ravine:
- FALLING ICE – Over the years, many people have been severely injured or killed by falling ice in Tuckerman. The most hazardous locations currently are in the center and right side of the ravine, including Lunch Rocks, Lip, and Center Bowl. Being low in Lunch Rocks, more aptly known as “Icefall Rocks”, is still not recommended. Being up high in Icefall Rocks has become more reasonable due to the Sluice ice, which typically looms above, has already crashed through Icefall Rocks.
- CREVASSES, HOLES, AND UNDERMINED SNOW – The most dangerous of these are in the Center Bowl over to the Lip on the looker’s right side of the Ravine. Falling into one has been the cause of numerous injuries and past fatalities. Generally, climbing up what you plan to descend will allow you to see most of these hazards for your descent and realize there may be large open spaces under the surface near these holes. Expect the recent snow to hide some of these threats.
- LONG SLIDING FALLS – Temperatures often fall below freezing even late into spring. Additionally, age hardening can create very dense alpine ice that remains very slick even on warmer days. Mountaineering experience, good judgement and proper equipment, like an ice axe and crampons, are your best defense. The bottom sections of popular runs are also melting uphill making it possible to fall into rocks and terrain features while still in steep terrain.
A section of the Tuckerman Ravine Trail is closed to all use. This is due to the severe consequences of a fall in this area. The closed section extends from the top of Lunch Rocks to the junction of the Alpine Garden Trail above the ravine. Only this section is closed. Hiking or skiing in the vicinity of the closed trail is not permitted. (ATTENTION AUX RANDONNEURS! Une section du sentier du Tuckerman Ravine est présentement fermé à toutes les activités. Cette section est située entre Lunch Rocks et le sommet du Headwall jusqu’où ce dernier rejoint le sentier du Alpine Garden. Cette fermeture inclut également toute activité de descente dans le secteur du Lip. Seulement cette section du sentier est fermé. Cette fermeture annuelle est due à l’ampleur des crevasses et à la gravité qu’occasionnerait une chute dans ce secteur.)
- Safe travel in avalanche terrain requires training and experience. This bulletin is just one tool to help you make your own decisions in avalanche terrain. You control your own risk by choosing where, when, and how you travel.
- Anticipate a changing avalanche danger when actual weather differs from the higher summits forecast.
- For more information contact the Forest Service Snow Rangers, or the AMC at Pinkham Notch or Hermit Lake.
- Posted 8:40a.m., Sunday, May 22, 2016. A new bulletin will be issued when warranted.
