Avalanche Summary

No new avalanches were reported in this region on Friday.

Snowpack Summary

Up to 20 cm of new snow covers sun crust on solar aspects and surface hoar averaging 5 mm, but found up to 20 mm, on sheltered, shady aspects extending into the alpine in some areas. A layer of small surface hoar (5 mm) buried in late February has been reported in isolated locations at treeline and below.In the upper/mid-pack you will likely find layers of crusts, facets, and isolated surface hoar buried 50-100 cm below the surface. Deeper in the snowpack, around 150-200 cm down there is a crust/surface hoar layer from January. Sugary facets near the bottom of the snowpack would likely be found in colder and dryer parts of the region, such as the far north.
