Shoestring Well Filled In

Location of Observation: Shoestring Gully at c. 2,200′
Shoestring Gully is in great, snowy condition for December. It showed signs of recent avalanche activity and windslab formation. A mitt pit at around 2,200′ in the first snowfield of the gully (WSW aspect) showed layers of one-finger-hardness windslab (about 30cm total depth) above 20cm of fist-hard facets. It took a fair amount of force to get the wind slab to shear from the facets below. (see photo)
Higher in this same snowfield was avy debris that we guess to be a day or two old. I’d estimate the debris to be about 25m in length, 5m in width, and varying from 30 to 100cm deep. The crown line may have been at the base of the next ice bulge. We couldn’t determine a trigger, but the debris made for good crampon-ing.
