Fresh wind lips were the only thing that we found reactive today. It was easy to kick off small chunks from these. Wind slab was mostly unreactive, except in unsupported terrain over 38º. When found it was small. Larger pockets of reactive wind slab could be waiting in steep leeward terrain. Test small, representative slopes first and approach larger terrain with caution.

Bottom Line

Yesterday's snow bonded well to old surfaces in Rattlesnake. We found no reactive storm slab. Wind slab is isolated and small but it is possible to kick of slabs in wind loaded terrain over 38º.
Basal facets can still be found under areas of shallow snowpack, despite warm temperatures for the past week. These facets are isolated and unlikely to cause and avalanche, but they are worth noting and planning for if you are entering steep terrain with a snowpack less that 4 feet thick.

Weather Summary

Cloud Cover:
Overcast
Temperature:
21º F (-
Wind:
Moderate , SW

The cloud ceiling hovered around 7400' today making for poor visibility at upper elevations. Winds were light to moderate out of the southwest. Temps stayed cool and yesterdays wet snow dried out making for decent skiing. The dry snow is available for transport although winds stayed light enough for this to be limited to the peak of Point 6.
