Location: Lobster Claw

Underneath the avalanche path known as “Lobster Claw” slabs of wind drifted snow were growing thicker and more dense. There is much variability of the snowpack in regards to where the wind has stripped and deposited new snow. I found the upper layer of the snowpack to be most worrisome and easily triggered by the weight of a human. I observed numerous natural loose dry avalanches pouring off the walls of Tuckermans Ravine. Two climbers in the area triggered a shallow wind slab avalanche while climbing in steep exposed terrain(photo 1). Cracking of the surface slab was noticeable in areas where snow was being deposited(photo 3).
