We drove up Bridger Canyon to look for wet snow avalanche activity. We observed 4-5 wet slab avalanches in Argentina Bowl that failed full depth, a full depth wet loose avalanche in the Pinnacles area, 6 full depth slab and loose snow avalanches north of Ross Peak and several full depth loose snow avalanches in the north of Frazier Basin. Additionally, there were many shallower wet loose avalanches. This activity occurred primarily on March 27th, but some occurred in the preceding days. Photo: GNFAC
