Avalanche Summary
No new avalanches were reported at the time of publishing on Thursday.
A few large (size 2) wind slab avalanches were triggered with explosives in the south on Monday.
A rider accidentally triggered a small wind slab avalanche below treeline near Window Mountain on February 11th. The wind slab had formed further downslope than normal.
Snowpack Summary
10 to 20 cm of light, dry snow fell near the Continental Divide on Tuesday with less as you go west.
Previous moderate to strong southwest wind and current light to moderate northeast wind have developed wind slabs on all aspects and at all elevations. In sheltered spots, expect 30 to 50 cm over the thick rain crust from early February.
Below this crust, the shallow faceted snowpack is generally well consolidated. There are two crust layers, one in the midpack and another near the base of the snowpack, that have been unreactive.
