Detailed Description
Muddy, water-saturated debris flow encountered on U.S. Highway 50 in Poncha Canyon on 15 July, 2014 about an hour after intense downpour from a localized thunder cell. Rock-laden flow was sourced from a steep, narrow tributary canyon (mouth visible in upper left part of photo) floored by loose rocky debris derived from underlying fractured Proterozoic bedrock.
