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.
This week's seasonably warm weather and lack of precipitation have allowed for stable snow conditions to prevail in most areas of the Ravines. Skiers and climbers have been capitalizing on this by making turns and climbing on a variety of snowfields and gullies. Our primary concerns still exist on north facing aspects that have not received solar gain this week. As yesterday's advisory mentioned, we observed some facet growth within an unconsolidated layer of snow that was sitting under wind slab in Left Gully. This is the reason that it stands alone in the Moderate catagory. Similar conditions may exist on the south side of the Bowl as well, so keep your eyes open if you are traveling in this area. We intend on checking this out again today to see if the facets are continuing to grow and weakening underlying layers. As for the rest of the forecast areas, you will want to keep your eyes out for isolated pockets of instability, especially as you move south in the Ravines.
Warm days and rain forecasted for early in the week will weaken ice in the ravines. Keep your eyes open for icefall and do not linger under suspected weak areas such as free hanging ice daggers and detached curtains.
The John Sherburne ski trail has mostly hard pack conditions. Anticipate water ice and rocks throughout the length of the trail. Be prepared for these hidden hazards and sudden changes.
THE LION HEAD WINTER ROUTE IS OPEN. This is a steep and challenging route. Ice axe, crampons, and the skill to use them well are necessary for safe travel. Remember, it is always easier to go up than come down.
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 reading mountain weather's effect on the snowpack, and avalanche rescue.
