Comments
We noticed a large slide on the north facing aspect of the ridgeline in the Butler Basin this morning around 8:30. It appears to be triggered naturally over night. We didn't see any ski tracks near the fracture, however we switched our transceivers to search mode to double check and didn't get any relay.
The slide was approx 400-500 ft wide and slid all the way down to the facets near the ground. In some places near the fracture line it appeared to be over 4 ft deep.
