Snowpack Summary

Very light accumulations overlie wind slab at higher elevations, settled storm snow and spotty surface hoar in more sheltered terrain, and a crust on previously sun-exposed slopes. A variable interface buried on Jan 23 is down about 15-35cm. In most locations it appears to be well bonded; however, buried surface hoar (up to 20mm) has been found in isolatedÂ parts of the North Elk valley. This will be something to watch as the overlying slab develops. The lower snowpack is generally well-settled.

Problems

Forecast light snowfall and strong west winds will create fresh wind slabs. Watch for triggering behind ridgecrests and in gullies.
