From obs 4/9/21: "...we saw widespread natural wind slabs on N-NE eastern slopes in the Northern Absarokas (photo). Winds increased throughout the morning, and evidence of wind transport became more apparent at higher elevations. We found that on aspects unaffected by wind loading, the new snow layer was not cohesive and only saw minor sluffing." Photo: E. Schreier

A small avalanche hitting the North Bowl Road.

Bridger Bowl is closed for the season and the ski patrol is on summer vacation. This means no one is mitigating avalanche hazards or closing terrain as conditions change, so skiers and riders have to make avalanche-related decisions for themselves and be prepared for partner rescue. It also means that familiar routes such as North Bowl Road may become unsafe. Photo: GNFAC

Some of the wet loose avalanche activity around Beehive Basin is getting large enough to be dangerous in its own right, other activity is dangerous because it could push us into hazardous terrain. Photo: GNFAC

Two natural avalanches in Sunlight Basin occurred on a heavily wind-loaded slope. Also, note the very large cornice overhanging the slope. Avoid getting on top of or underneath these large overhangs of snow as they can break unpredictably. Photo: GNFAC

Fro obs: "... an avalanche we saw out by Goose Lake yesterday (3/27)... we are pretty sure this wasn't there at 8am. On the way back (5pm) we noticed this large avalanche on the NE face of Iceberg Peak at about 11,200. It broke naturally in the new snow which was drifted heavily by SW winds (20-40mph all day). It appears to be 3-4' deep at the deepest spots, 600' wide, and ran 750'. There is a small area below the upper crown that stepped down, but tough to tell if that was just snow from the start of this storm. We did not notice any other activity in the area..." Photo: M.

From obs 3/28/21: "Saw this slope which frequently slides had been triggered on our way out last night [lower left in photo]. Slid to the ground but I expect it was mostly new snow as there is a larger old crown visible further uphill... I did see two other small pocket slides yesterday also in new snow on bed surfaces of older slides... General snowpack is getting very deep now but a thick junk layer remains at the ground everywhere I dug sleds out." Photo: J. Gerardi
