The Colorado Avalanche Information Center (CAIC) said the slide occurred near Treasury Mountain in the Elk Mountains southeast of Marble. Nobody was injured. It was ranked a D1, meaning it was “relatively harmless to people” on the D-scale, which ticks up to D5 to indicate the most dangerous and destructive slides.

“This setup reminds us that even small early-season slides can happen on steep slopes where you find ~10 inches or more of consistent snow,” CAIC wrote on social media.
