Snodgrass study pit

CB Avalanche Center2020-21 Observations

Zone: Southeast Mountains

Location: E facing knoll on Snodgrass

Date of Observation: 11/26/2020

Name: Jack Caprio

Subject: Snodgrass

Aspect: East

Elevation: 10,000

Avalanches: None observed

Weather: Scattered clouds, sun coming in and out. Temps around 20’s. Light winds less than 10 mph out of the south.

Snowpack: I tested the snowpack on an east facing aspect below treeline. I found thin melt freeze crust at depths of 20 cm and 15 cm with F hard facets above and below. Sitting on the bottom of the pack are 15 cm of 1-1.5 mm facets

No exciting propagating results in stability tests. However, both the fractures on CT and ECT collapsed on the interface of old faceted snow and the melt freeze crust at 15cm. This weak layer crust has the potential to initiate, but it is unlikely to propagate.
