Avalanche Summary
Several size 1-2 wind slabs were reported in steep terrain in a deep snow area in the Howsons on Sunday. No other new avalanches have been reported in the region since last week, when 2 large cornice triggered slabs were reported in the Microwave area. Slab avalanches are most probable at higher elevations that haven't been through daily melt-freeze cycles.
Snowpack Summary
Up to 20 cm of dry snow may exist on northern aspects above 1300 m, with isolated wind slabs in exposed terrain. Periods of sun and high daytime freezing levels have developed crusts below treeline and on sun exposed terrain at all elevations. The snow may be moist or wet below treeline during the warmest part of the day. The February crust and facet layer was reported to be down 75-90 cm in the Houston Telkwas sled area. The deep persistent weak layer of facets and/or a crust that were buried early in the winter are still lingering near the bottom of the snowpack.
