Huntington Ravine also has both LOW and MODERATE avalanche danger. The Escape Hatch, Yale, Damnation, and North gullies have Low avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikely except in isolated pockets. Normal caution is advised. South, O'dell's, Pinnacle and Central Gullies have Moderate avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible. Use caution in steeper terrain.
Well we will take what we can get, the Summit reported a little over 2" (5cm) of snow from yesterdays storm. Here at Hermit Lake we recieved 2.4" (6.1 cm). With the winds starting from the S and moving around to the W, NW the N through E aspects received the bulk of this new snow. The new snow is sitting on a very hard surface waiting for the right trigger. Areas that are posted at Low do have isolated pockets of wind slab. We received a report that folks encountered more than 12" of new snow in Right gully yesterday. Remember just because the Summit only received a couple inches doesn't mean that Ravines did not pick up more from the winds transporting this snow. Your best bet is to stay on old surface when possible. This morning's blue skies are forecasted to give way to increasing clouds. A low pressure system is forecasted to be moving in later today bringing us the chance of light accumulations of snow late tonight and into tomorrow. Winds are expected to stay relatively light.
After telling you that you should stick to old surface where possible the other hazard to be conscience of is the extraordinarily hard old surface conditions. To call it bullet proof is truly an understatement. Crampons, an ice axe and solid technique are a must in most areas on the upper part of the mountain today. Our snowpack is better described as an "icepack" and self-arrest would be very difficult to execute successfully. Use caution and be honest about your skills and mountaineering experience.
The Lion Head Winter Route is open. Mountaineering skills and equipment are required for safe travel on this route.
The Sherburne Ski Trail is open with thin cover and varying conditions. New snow is covering long sections of water ice, deep waterbars and water channels that can grab a ski tip very quickly. New snow is helping to improve our thin icy conditions but we do need much more.
