"I skied near Quake Lake today, and observed several signs that the snowpack has not adjusted to this last storm yet. While ascending, several drifts collapsed under my weight, and I observed a very recent natural slide on a wind-loaded, east facing slope at about 9200'." Photo: Sam Reinsel

Cornices within Bridger Bowl have grown large since the ski area closed and stopped avalanche mitigation for the season on March 15th. Photo: GNFAC

Observed this 8-12" slab on 3/30/20. Appears to have been triggered by cornice fall. Also observed several small wet loose slides from previous day and this morning. Photo: GNFAC

Cornices on the back side of Sheep mtn are getting huge. Guessing well over 25ft. They are right above a play area to the west of Ovis lake, and round Round lake. Photo: R. DeSilva

The red dashed lines mark the sides of the shallow avalanche that broke on surface hoar. It was triggered by a snowmobiler on 29 March in First Yellowmule (N aspect; 9500'). Photo: GNFAC

We dug this pit adjacent to a snowmobiler triggered avalanche. It broke on the surface hoar layer which is located at the top blue crystal card. The bottom card denotes the larger grains of facets that formed early in the winter. Photo: GNFAC

This surface hoar crystal is almost 1.5 cm (each square is 2mm) and was the weak layer in a few avalanches on Buck Ridge (3/29/20). Photo: GNFAC

Northern Madison, 2020-03-30

There were many tracks in Buck Ridge and only a few small slides in First Yellowmule. This picture is looking SW towards Sphinx Mountain. Feathery crystals of surface hoar are buried 1-1.5' under the surface and are a concern. This layer seems to be more prevalent in protected areas. Photo: GNFAC

We saw this natural avalanche from afar. It was NE aspect and likely failed on a layer of surface hoar 1-1.5' deep. The Madison Valley is in the background. Photo: GNFAC

From obs (3/29/20): "...in Maid of the Mist basin there were multiple loose wet avalanches [and a slab] caused by a piece of the cornice falling off on Pt. 10201." Photo: N. Salsburg

From obs (3/29/20): "This 44* slope failed 12” under the surface of the snow on a hard crust as we descended to help another stuck rider in a tree. Another layer exists 2” below the failed layer which persisted to follow me down the hill rupturing as fault lines as I continued rapidly down the hill after extracting the stuck rider. While the remaining slope only fractured without chasing me down the hill... "Photo: TJ Krob

Sunday (3/29/20) skiers near Fairy Lake saw this cornice collapse that ran for quite a ways in October bowl. Photo: T. Gittins

Northern Gallatin, 2020-03-29

From obs. (3/29/20): "Significant wind started building mid morning, forming even bigger cornices and wind loading many slopes. Noticed this slide on an East/Northeast aspect at the back of the bowl above Maid of the Mist creek, possibly triggered by cornice fall but unknown. Happened between 9:45am and 11:30am today, as at 9:30am it was not there, and when we returned to the spot around 11:30am the slide was visible." Photo: CP

From email on 3/27/2020 : "natural slab avalanche I observed today near Cooke City.  An easterly aspect around 9,400'.  I'd estimate the crown to be 2-3' deep and about 100' wide.  Looks like it was triggered by a cornice fall (2-3 days ago?)."

From obs: "This slide popped on a N aspect at 9000', ranging from 18-30 inches deep... it slid on a crust." Photo: N. Iltis

Lionhead Range, 2020-03-27

Today on the east side of Lionhead Ridge we found a layer of weak, near-surface facets buried under a foot and a half of new snow. This is definitely something to watch out for especially on wind-loaded slopes. Photos: GNFAC

Today we rode into the Taylor Fork and Lionhead areas to remove our weather stations for the season. Photo: GNFAC
