Tuckerman Ravine has LOW, MODERATE and CONSIDERABLE avalanche danger today. The Little Headwall has LOW avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikely except in isolated pockets. Normal caution is advised. The Lower Snowfields, Hillman's Highway and Left Gully have MODERATE avalanche danger. Natural avalanches are unlikely and human triggered avalanches are POSSIBLE. Unstable slabs are possible in steep terrain. Use caution in steeper terrain. All other areas in Tuckerman Ravine have CONSIDERABLE avalanche danger. Natural avalanches are possible and human triggered avalanches are probable. Unstable slabs are probable on steep terrain. Be increasingly cautious in steeper terrain.
Huntington Ravine has LOW avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikely except in isolated pockets. Normal caution is advised.
If you are heading into avalanche terrain today, be aware that a variety of snow conditions exist. In Huntington Ravine there is a lot of old surface showing with intermittent patches of wind slab. In some areas this wind slab may be very hard and in others it may be soft. Try to stay on the old surface whenever possible. Isolated pockets do exist, so use your avalanche skills to find a good route and travel wisely. Areas in Tuckerman Ravine also have a similar variety of snow conditions, however, areas of wind slab are more prevelant. Realize that avalanche skills are required to travel safely through any avalanche terrain. Areas of most concern are on the northern side of the Ravine, such as the Lip, Sluice, and Right Gully. We feel that human triggered avalanches are PROBABLE in these areas, hence the CONSIDERABLE rating. If you are heading out today, be prepared for Arctic weather conditions. It is currently 0 F (-18c) at Hermit Lake. The forecast is calling for falling temperatures today with increasing winds. BRRRRR! Be prepared.
AS ALWAYS, THIS ADVISORY IS ONE MORE TOOL TO HELP YOU MAKE YOUR OWN DECISIONS IN AVALANCHE TERRAIN. It should be used along with your own snow stability assessments, knowledge of safe travel techniques, skill in mountain weather's effect on the snowpack, and avalanche rescue.
THE WINTER LION HEAD ROUTE IS OPEN. The route leaves from the Huntington Fire Road and has orange signs starting on the Tuckerman Ravine trail at roughly the 1.8 mile mark. It is a steep and challenging route. Crampons, an ice axe, and the ability to use them with skill are required for safe travel. Avalanche skills are always required to travel safely in the mountains. Be prepared to do your own stability assessments.
The John Sherburne ski trail has improved over the week with wind moving snow in here and there over the entire length of the trail. There are a few problem waterbars and rocks still hidden just under the new snow.
