Since Wednesday, both natural and controlled avalanche activity has been mostly limited to loose dry sluffs of diminishing size. A size 1 skier accidental storm slab was reported on a north aspect at 2000 m, with crown depth 10-30cm.

A widespread natural cycle occurred during the storm Monday night through Tuesday, storm slabs size 2-3 and loose wet size 1-2.

Have you been out and about in the mountains? If so please submit your observations to the Mountain Information Network (MIN). It doesn't have to be technical - photos are especially helpful! Thank you so much for all the great MINs submitted so far! 

5-10 cm of dry snow sits over a crust that formed at all elevations during the warm, wet storm earlier this week. 

At treeline and below, the crust continues to harden with cool temperatures but may still be somewhat punchy, with a moist snowpack below.

In the alpine, the crust is supportive. Sugary facets sit sandwiched between this surface crust ontop, and an ice lens up to 50 cm below the surface. The ice lens formed from the freezing rain that fell on the old snow surface at the beginning of the previous storm. Above 2100 m, it has been a failure plane for avalanches since the storm.

Snowpack depths change rapidly with elevation, from 50-100 cm around treeline to over 150 cm in the alpine.

• Minimize exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
• Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
