From obs 1/28/23: "There were numerous debris piles, point releases, and crowns on the north face of Elephant and the northeast face of Blackmore this morning.  Most of them appeared to have run during the storm (1/27) and had been covered by at least 6 inches of new snow." Photo. S. Regnerus

Fairy lake today (1/27/23), remote trigger from top of the ridge

About 2-2.5ft deep about 75-100 ft wide

Observed two recent natural avalanches on 1/25/23 that broke 1-2 feet deep, presumably on a surface hoar layer. There was a couple of inches of snow on each of these slides, so I would place them between three and five days old. The slides were R1-D1.5 in size - 75-100' wide, 1-2' deep, and 100' vertical fall. Photo: GNFAC

Skiers near Mt Blackmore noted loose snow avalanches with ski cuts. This one slid for about 50 feet on a 34 degree slope. This location did not present any signs of significant wind loading. Photo: E. Schreier

Surface hoar can often be seen as a grey stripe on the wall of your snowpit as was the case at Bacon Rind in the Southern Madison Range on 1/23. Photo: GNFAC

Observed this cornice fall triggered slide morning of 1/19/23. It was not there the previous morning which was sunny and clear. Photo: GNFAC

From Big Sky Ski Patrol 1/21/23: "skier triggered a surface wind slab in Wyoming Bowl that broke 8-12” deep. It propagated to an estimated 150’ wide- SS, R1/D1.5... The slide was small, no one was hurt, and the avalanche was reported (which we appreciate), with no further public involvement other than the trigger."
