THIS IS THE LAST ADVISORY FOR THE SEASON. HAZARDOUS CONDITIONS WILL PERSIST UNTIL COMPLETE MELTOUT SO PLEASE READ THIS FINAL ADVISORY BEFORE HEADING INTO THE RAVINES OR TO THE SUMMIT OF MT. WASHINGTON.

This General Advisory will be in effect until complete melt out later this summer. The snow coverage that is left has settled out, been skier compacted, and is going through the late season melt-freeze process. However, the remaining large snowfields may make for a good sliding surface for late season avalanches. A June snowstorm is not an unheard of occurrence on Mt. Washington. Be prepared for the possibility of new snow instability if this occurs.

A SECTION OF THE TUCKERMAN RAVINE TRAIL IS NOW CLOSED TO ALL USE. This section extends from Lunch Rocks at the floor of the Ravine to the top of the Headwall where it meets the Alpine Garden Trail.  This includes no skiing or riding through the Lip area. Only this section of the trail is closed. This annual closure is due to the magnitude of the crevasses and undermining, and the severe consequences of a fall in this area. The trail will reopen after the last snow has melted off.  Check in with one of the local visitor centers to determine the status of the clousure before starting up.  If you use motorized access to the summit of Mount Washington it is NOT recommended that you descend any route through the Ravines.  You will not be aware of the hazards below you.  Many have attempted this over the years, often resulting in severe accidents.

BE AWARE OF FALLING ICE. Each year over 1000 tons of ice form on the steep slopes of Tuckerman Ravine. In the spring it all falls down, often in pieces larger than cars, and often over popular locations like Lunch Rocks and the Tuckerman Ravine trail in the bottom of the ravine. This hazard will persist until complete melt out. The best thing you can do to protect yourself is to avoid spending time in the potential path of falling ice. CREVASSES AND UNDERMINED SNOW appear as the snow pack melts and separates from the ledges on the Headwall. These openings vary tremendously in size and include the many waterfalls on the Headwall.  Skiers and climbers need to pay attention to what is below at all times and constantly evaluate the potential outcome of a fall or slide.

We sincerely thank all the groups and individuals that helped us make it through the season successfully. We couldn’t do the job without the many volunteer hours spent carrying injured people down the mountain, giving out good information to visitors, and giving us financial support. Thanks for a great season and we’ll see you next winter. Joe, Jeff, Frank, and Chris.

Expires at 12:00 midnight, Sunday, May 25, 2014.

Tuckerman Ravine is under a General Advisory and will be in effect until complete melt out later this spring/summer. You will need to do your own snow stability assessments when traveling in avalanche terrain.  General Advisories are valid for no more than three days, but may be updated earlier as conditions warrant.  We are no longer monitoring conditions in Huntington Ravine.

Recent heavy rain has continued to melt snow cover in the ravines. Melting and undermining will continue as showers and, potentially, thunderstorms plague us this coming weekend. The unsettled weather will undoubtedly reduce visibility at times at higher elevations and make navigation more challenging.  Left Gully and Hillman’s Highway are both skiable but have obstacles to avoid and are no longer full length runs due to the shrinking snowpack at the top and bottom.

FALLING ICE. Over the years many people have been severely injured or killed by falling ice in Tuckerman. The most hazardous locations are in the center and right side of the ravine, including Lunch Rocks, the Sluice, and under the Lip-Center Bowl area. Other areas pose this threat as well, though to a lesser extent.   Large rocks may provide some cover, but have proven to be inadequate shields for people hiding behind them. Lunch Rocks is a hazardous location when icefall is a possibility and should be avoided!

CREVASSES AND WATERFALL HOLES are another potentially deadly hazard. Each season these form in many areas, the worst being in the Sluice, Lip, and Center Bowl. Give them plenty of room, since they are often much larger beneath the surface than what you can see from above and can be much deeper than you might expect. UNDERMINED SNOW is a close relative to crevasses. It occurs when streams have eroded away the snowpack from below, but left behind a bridge of snow. This bridge can collapse without warning under your weight, bringing you into the icy stream below. Give wide berth to areas that have already collapsed or show signs of sagging or cracking.

LONG SLIDING FALLS are the #1 cause of injury each spring. Cold temperatures cause soft snow to refreeze into a slick alpine ice.  Always think about your fall line below and pick routes that minimize going over cliffs or into rocks. We always recommend an ice axe and crampons for travel in steep terrain. If the unexpected does occur, having the ability to use these tools effectively can save you from serious injury or worse.

A SECTION OF THE TUCKERMAN RAVINE TRAIL IS NOW CLOSED TO ALL USE. This section extends from Lunch Rocks at the floor of the Ravine to the top of the Headwall where it meets the Alpine Garden Trail.  This includes no skiing or riding through the Lip area. Only this section of the trail is closed. This annual closure is due to the magnitude of the crevasses and undermining, and the severe consequences of a fall in this area.

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.

  • Anticipate a changing avalanche danger when actual weather differs from the higher summits forecast.  For more information contact the Forest Service Snow Rangers, the AMC at the Pinkham Notch Visitor Center, or the caretakers at Hermit Lake Shelters.
  • Posted 7:15 a.m. Friday, May 23. A new advisory will be issued no later than Monday, May 26.
