From obs: "The slide was triggered Monday afternoon by us climbing up the slightly lower angle slope to the left. It was an East facing slope at 9400’ above Muddy Creek drainage. We triggered lots of sluff slides in the new snow. This small wind slab was the most significant action we got or saw all day, however, we mostly stayed well away from obviously loaded steep terrain."
