This is the deposition from an avalanche that ran a few miles from my house on Saturday afternoon, 7 May. For those of you who know Colorado, this happened next to Interstate 70, between Frisco and Copper Mountain ski area. The flat topped mound of snow on the right side of the second picture is the bicycle path from Frisco to Copper Mountain Ski Area and onward to Vail Pass. It might be a while before it's rideable this year...
This area is fairly deep in the canyon and west facing, so it gets very little sun all winter long, so very little of this winter's snowfall had melted. We had a series of heavy, wet snowstorms at the end of April to pile on a last good load of snow, then things finally warmed up a few days before this happened. A few days of warm temperature to melt the snow and lubricate the ground underneath the snow, some strong sun all day Saturday that finally loosened up the snow, and here's the result.
