Since Thursday, 2-3' of snow and 2"+ of SWE has piled on our snowpack reactivating layers buried mid-pack and near the ground on northwest through southeast slopes. Over the past few days riders remotely triggered slides from above, below and observed large natural avalanches like the one below. Failing 2-6' deep and breaking wide, these are unsurvivable avalanches and the conditions are ripe for triggering one of these monsters. There is no threading the needle today, and it is crucial to avoid any avalanche terrain where this problem lives.
A large destructive avalanche at 10,400' on a northeast slope that occured naturally, and gouged to the ground near Chalk Creek.
