This slide on Yamaha Hill may have occured yesterday, but not sure on the trigger? There are some sled tracks nearby which could have made this a remote trigger?
Comments
This slide in the Super Bowl area likely ooccured early in the week when the area was going through a pretty good natural avalanche cycle. Many of the slides I observed have some east in their aspect and the slides broke to the ground.
Comments
This small slide looks to be fairly recent, possibly yesterday and my guess is that it was triggered from a distance lower on the slope.
Comments
I triggered this slide while walking the ridgeline on a northeast facing slope. I experienced a collapse first, then observed the crack and moving slab. The crown was 3' deepx50' wide and ran about 150' vertical. Recent new snow and steady winds have likely overloaded the buried faceted snow that was located in the middle of the snowpack.
