Some recent avalanche pics

Below are two recent pictures of avalanches from near Silverton, CO, taken by Mark Rikkers. Mark is a former CU-geography undergrad and graduate student in snow hydrology who now is a profession avalanche expert working for the Colorado Avalance Information Center. He forecasts avalanche danger for the Red Mountain Pass/ Silverton/Ouray area and works with C-DOT on avalanche control work on highway 555.
