Cooke City, 2024-12-30 We were ski touring on the SW side of Mt. Henderson today, and noticed a large (natural?) avalanche on the NE aspect of Henderson. First observed at around 1:15pm. It appeared to be very fresh, possibly from a remote trigger this morning. 2 photos attached. A NE aspect, around 10,000'. It looked to be 4-6' deep and about 500' wide. And it failed on snow at/ near the ground. Photo: B Fredlund Link to Avalanche Details |
