Avalanche Details

We witnessed Hippy Bowl avalanche at ~1345 today. See Sean Fallon obs for the details. Also..... drove South thru the Pass at about 1545 and saw a large skier triggered avalanche on the SW face of Sunburst. No details other than I saw a single ski track entering the crown at the apex, as viewed thru binos. Word is that nobody was caught.... fortunate as it would've been a really rough, bumpy ride this early season.
