Avalanche Summary
No new avalanches were reported on Saturday, Sunday, or Monday.
Snowpack Summary
Surface hoar is growing on all aspects at all elevations up to 12 mm, even on ridgetops.
South through west aspects are stripped down to a thick crust that formed early in February. This crust exists at all elevations. On north through east aspects you will likely find old wind slabs over this crust. Due to recent cold temperatures, weak sugary snow crystals are forming under these wind slabs, which means they may be more likely to slide on the crust.
In treeline terrain that is sheltered from the wind, 15 to 25 cm of settled snow sits above the crust.
