Tahoe National Forest Sierra Avalanche Center

HS >3.6m, unable to probe to ground. Pit dug to look at potential wet slab setup on Mar 24 surface hoar layer.

Pit dug in open near treeline terrain to look at March 24 surface hoar layer and to gauge the depth of free water percolation.

Pit dug in near treeline terrain to look at recent storm snow instability.

Pit dug in below treeline terrain adjacent to deep slab avalanche from 1815h the day prior. It is unclear if the avalanche failed on the graupel layer or the facet layer.

Pit dug at the crown of a deep slab avalanche that likely occurred on 03/18/2020 more info here:https://www.sierraavalanchecenter.org/observation/2020/mar/18/1100/martis-peak

Buried facet layer below recent storm event is showing some signs of gaining strength. No known avalanches have been reported on this weak layer.
