Notes

A snowmobiler triggered an avalanche from the bottom of the slope as he rode past a gulley below Sheep Mountain. The avalanche barely missed him. The avalanche was approximately 100' wide and 2' deep. It failed on a wind-loaded slope, ESE-facing, and was large enough to bury or injure a skier or rider.
