Location: Tux & Huntington Ravines

Clear skies allowed for good visibility of the alpine starting zones. The winds were calm in the floor and moderate on the ridgelines above with obvious blowing snow.
Huntington revealed a scoured snowpack with very little accumulation on wind exposed slopes. The trees offered a wind effected 2-3 inches of new snow. Much of the surface snowpack was knife to pencil firm refrozen crust with isolated pockets of wind drifted snow. Not much for recent avalanche activity here.
In Tuckerman’s Ravine we observed several mid-storm avalanches including: Hillman’s, Left Gully, & Chute. Left Gully had 2 distinct crown lines, one 2/3 of the way up and another just below the ridge. Debris is piled on top of the remnants of two slab avalanches reported on Sunday and Wednesday. Similar surface conditions exist here but with thicker slabs of wind drifted snow on top of the pre-existing hard crust. Reports from Lobster Claw indicated that the thickness of some slabs is up to 22 inches thick and poorly bonded to the crust below. The party chose to not ski the line.
