Wind Loading BTL on Snodgrass

10webCBAC Observations

Date of Observation: 02/22/2023
Name: Sam Ridley

Zone: Southeast Mountains
Route Description: I skied from Snodgrass TH out 317 to the 1 mile shots and did laps there and above the road on the way back between 9am and 1pm. I was primarily on N through NE facing BTL terrain.

Observed avalanche activity: No
Avalanches:
Weather: There were variable moderate to strong winds, primarily from the SW. Precipitation intensity generally increased throughout the morning, ranging from none to around an inch per hour. There was significant snow transport BTL in less sheltered areas to north facing terrain.
Snowpack: Wind sheltered areas had 6″+ of new snow, which sloughed easily on steeper test slopes but I did not find cohesive slabs in the trees. More open, wind loaded N to NE facing slopes near the road had 1.5’+ new snow, shooting cracks, and were getting deeper, stiffer, and easier to initiate cracks in throughout the morning.
