Slide on Whetstone

CB Avalanche Center CBAC Observations

Date of Observation: 02/11/2022

Zone: Southeast Mountains
Route Description: Through cement plant up a well established track. Lots of skiing done here, tracks all through the woods and gullies. coming out of the woods going up the standard ridge pointing north. About 2/3 up on the ridge leading to the flatter part we were right on the rounded edge on a 20 ish degree slope. If you would have bet me will it slide here I would have bet $100 with 99.999% certainty that this would never go. I would have lost that bet. 27 years in the backcountry, go figure.

Observed avalanche activity: Yes
Avalanches: We heard a whoomp, I looked thinking it would just settle as it usually does, but in a moment it started moving and both skiers fell. Due to low angle movement was very slow, both skiers got held up in trees just 25 feet lower. In all a minor event, one lost pole no injuries, but a definite wake up call. The crown was all of 10″ tall tapering to 4″ to the north west. The whoomp propagated to the south around the edge of the ridge and set off another 45ft wide sluff of blocks 8 inches thick that ran down about 500 ft from the crown. It propagated to the top of the ridge about 100ft above the trigger.
Weather: Sunny, no wind, not too warm, but not too cold.
Snowpack: no new snow in weeks, an aging snow pack.
