Comments
I want to provide some additional information to this prior reported slide in Logan Dry Canyon - DB. There is a 3' crown at 8500 feet elevation. The avalanche may have started higher under the cornice (8700 feet) or part of the cornice broke off - but hard to tell. A pocket 200' wide and 300' vertical also pulled out at 8000 feet on the east side of the gully (first photo). Possibly this was a sympathetic slide to the main slide.
The slide ran all the way to bottom and crossed the summer trail (2 photos). At the bottom, it ripped out a swatch of trees about 100 - 200 feet wide and created a new exit path from the gully to the trail.
I am also attaching a photo taken Wednesday of the upper portion of the slide path from pt 8031 feet across the way below the Folly. Here you can see the multiple flow paths. At the time (Weds), I noticed a lot of missing brush in the main slide path but could not tell I was looking at an avalanche.
For timing, I think sometime between Feb 15 and Feb 28. There was fresh snow and a fresh set of tracks on the debris pile at the bottom. So at least one storm cycle ago.
This slide probably ran in the same cycle as other slides in Exit, Goal Post, Logan Peak Cirque, and the Logan Peak Diamond West.
The slide in Exit ran two or three storm cycles ago as at the bottom there were ski tracks that were mostly filled in from last week's storm..
