High-pressure makes its last stand today with another round of unseasonably warm temperatures before a return to more winter like weather and temperatures Tuesday. The mid-January sun is now strong enough to impart some heat into the snowpack. As a result, the snow at lower elevations has receded and thinned somewhat while mid and upper elevations solar aspects have developed a melt/freeze crust of varying thickness and maturity, depending on aspect, elevation, and solar exposure. The last significant snowfall was on 1/9, which brought ~ 1 -1.5’ of snow followed by a post-storm winds (Wednesday, 1/10) which formed stubborn Wind Slabs throughout the eastern Sierra, resulting in a small skier triggered release reported on the 11th near Crystal Lake as well as numerous naturals along the Crest and Virginia Lakes. Thursday, light snow showers moved into the region briefly along with moderate to strong Southwest winds leaving a dusting of snow in middle and upper elevations and a thin wind crust and Wind Slabs on cold northerly aspects and on shaded slopes. Since then, unseasonably warm temperatures have helped snow settlement. The complexity of the snowpack, especially on cooler northerly aspects, is further complicated by uneven patchy distribution of the early season snowpack. The deeper early season snowpack consists of alternating poorly bonded melt/freeze crusts and faceted sugar snow, which can be found below the recent snowfall (1/9) in the snowpack. Reports of Whumphing near Duck Pass illustrate the complexity of the snowpack and the varied spatial distribution of the Persistent Slab problem. The Persistent Slab problem will likely continue to be a concern for a while. With that in mind, it is important to assess the snow stability of the terrain before committing to ride. Evaluate the snow and terrain carefully and identify areas of concern.
