Notes

2/18/21 at 11:45 GNFAC forecaster observed with binoculars natural avalanche activity within new snow along ridgeline south of Bridger ski area to Bridger peak. There were two 50-100 foot wide slabs that broke in the recent storm snow, in the Pinnacles and on Bridger Peak. Wind was blowing strong from the west and there was a lot of snow transport. Cornices were very large and some had broke and gouged through the recent new snow and ran long distances a few triggered broader loose snow avalanches.
