I saw this fresh rider remote triggered avalanche around lunchtime from the ridge above Hell's Kitchen.... The avalanche is on Competition Hill in Crescent Lake Canyon, just a bit north of a close call on 2-22-2012, where a rider was caught and carried by and avalanche, but stayed on his machine and rode out of the avalanche. Notice the horizontal cracks across the bowl near the top of the snowmobile tracks.... I found flattened surface hoar or frost crystals on the bed surface of the avalanche... In the crown, the surface hoar buried on 2-8-2012, was evident a couple inches below an eggshell rime-crust....
