Notes

From obs: "Today (03/26/2024) there were strong winds loading snow onto the Northeast face off of Pine Martin Ridge, just North of Ram Pasture. When we got a better view of the slope, we noticed there had been a natural wind-slab avalanche (left), possibly triggered by a cornice fall. While transitioning, we saw a small part of the same cornice break off and trigger a similar wind slab avalanche (right). "
