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"
