Dry Loose on Ross Pk.

Date
Activity
Skiing

Skied the Banana Coulior off Ross today. 6-8" of fresh, dry snow has fallen and lies above a bomber crust that was observed on all aspects we traveled on. The weak interface between new, dry snow and the pervasive crust allowed for a large sluff, or dry-loose slide, that began near the top of the Banana Coulior and ran for ~ 500'

Notes

From obs on 04/17/2024: "Wet slab 150-200 ft across, SE shoulder of Abundance towards Wolverine. Looks to have maybe happened before new snow. New snow 6-8 was extra funky, 2-3 powder on a rain? crust on heavy wet. Bonded to unsupportive melt freeze on completely saturated glop. Lots of short running sluffs"
