Notes

A sledder triggered an avalanche on a wind-loaded slope near Goose Lake. It was maybe 75-100 feet wide but only slid 3 feet before arresting. It was on a low-angled slope and failed on facets on a rocky band. They triggered it as they were sidehilling and rode off the slab. Doug interviewed the party in Cooke City.
