Weather

Warm and calm on the East aspect.

Snowpack

Traveled on predominantly east-facing terrain between 10k-11,600ft.Found the top 8-10cm of a settled 20cm slab to be wet by noon. A 10cm 1F crust interface is layered beneath which remained supportable to both skis and boot pen after 2pm. Still experiencing collapsing of the snowpack on the high sides of cross loaded gullies connected into northeast terrain. Though no cracking and/or movement of a slab. Found moderate-hard snowpack test scores NTL @ ~11,400ft with Q3 failures in the 2/21 dust layer and hard failures beneath the crust. On Northeast, moderate snowpack test failures remain at the bottom of the settled slab and buried near surface facets. The slab sampled at this site seemed more stubborn and failed with less energy than observed the previous day.
