A skier noted, "Newish slide with a fresh looking debris pile. Between Alex Lowe and Peak 9806. Appeared to step down into the old snow. Looked like a D2.5-R3, natural trigger." Photo: F. Madsen

We triggered this avalanche remotely from about 50 feet above the crown up on the ridge. The crown was 1-2' deep, 100' wide, and ran between 200 and 300 vertical feet through trees and cliffs. Another slide failed sympathetically at the same time, 100' down the ridgeline. The slides failed on a 40 cm thick layer of depth hoar, which composed half of the snowpack. Photo: GNFAC

Cracking and collapsing on a 31-degree slope near the Lionshead area down south. The slab was 3-4' deep, and the slope was on the verge of being steep enough to avalanche. From the email: " fractured about 20’x10’ area initially, maybe 3-4’ deep. We got off the hill and it continued to fracture in bigger spots but did not slide more than a foot total." Photo: S. Thompson

Bridger Range, 2019-01-27

Skiers in the Bridgers saw multiple large natural avalanches in the Bridgers that had released during recent snow and wind loading. From the email: "Looks like things really went off in the Bridgers in the last few days. Loads of natural avalanche activity, much of it appearing to fail on deeper layers than the new/old interface." This is the third large avalanche that has been reported on Bridger Peak this season. Photo: B. VandenBos
