From email: "This avalanche was triggered by a rider in our group on the 7th. The rider was midway up the slope, it broke above him right under the cornice and he successfully outrun the avy to the bottom. Right above the trail it looked the deepest at 10' to 12' deep at the peak and 6' plus further to the north."
From obs on 03/08/2024: "We rode out to the avalanche that was triggered yesterday on Henderson Mtn. It broke over 2000' wide (measured on GPS) and all the way up to the ridgeline, 6-10' deep and maybe 12-15' deep at the deepest section. There were a couple hundred feet of slope that had not slide between this one and the similarly large slide to the north last weekend. The deepest debris was probably 15-20"

Saw this avalanche in East Hayden from the Roost today. Likely happened yesterday, 3/6. There are a couple smaller crowns lookers right of the bigger avalanche. Looks to be D2
