Northern Gallatin, 2019-03-22

This wet slab was observed on Friday (3/22) across the Sourdough canyon trail, about 1.4 miles up. It put 4-6 feet of debris lower down in the creek. Although small, a heavy wet slide like this can be powerful and very dangerous. Current warm temperatures are a shock to the snowpack, and steep slopes should be avoided if the snow is wet. Photo: P.

Southern Madison, 2019-03-22

A snowbiker was partially buried in a slide on the west side of Sage Peak in the southern Madison Range. The slide occurred on a southwest facing slope at 8,700 ft. and failed on weak snow near the ground. The wet slab avalanche was triggered as the biker was side-hilling across the slope. He was caught, carried and buried to his chest, but fortunately escaped unharmed. Photo: D. Talbert

Two wet slabs that looked to have released during the past 48 hours. The smaller slide on the left had a debris pile that was 6' deep. The larger slide on the right failed at the ground and took most of the snow in the chute with it. The large slide may have been triggered from smaller loose wet slide that was set off by a skier.

Outside Cooke City up Zimmer Creek, a skier spotted this cornice fall which triggered a small pocket down low. Photo: F. Madsen

Cooke City, 2019-03-21

Many wet loose and wet slab avalanches were seen near Zimmer Creek (north of Cooke City) on south and east aspects. Temperatures were warm at 10,000 feet. Photo: F. Madsen

Wet slab avalanches will be a growing concern as free moving water travels through the snowpack. This problem is most likely on mid to low elevation slopes that have a shallow snowpack and poor structure. Be aware of wet slabs as temperatures warm and the snowpack becomes increasingly unstable.

Warm temperatures are causing large cornices to lose strength. Be cautious when traveling on slopes below cornices and give them a wide berth along near ridgelines. Photo: GNFAC 

Northern Madison, 2019-03-20

Above freezing temps and direct sunshine are creating unstable conditions on steep sun-exposed slopes. This problem is most common in steep rocky terrain or areas with a shallow and weak snowpack. Move to shadier aspects or away from steep terrain if point releases are occurring. Photo: GNFAC 

Lionhead Range, 2019-03-20

This photo near Lionhead, is indicative of the wet loose avalanches we are seeing on many low elevation, south facing slopes throughout our advisory area. Daytime temperatures near 50F will make avalanches like this more frequent and widespread in the coming days.

Cooke City, 2019-03-17

A small wet loose and slab avalanche on a SW facing slope near Daisy Pass. These slides were observed on March 17th, 2019. The wet loose looked at least a day or two old, the small slab a bit older. The slab broke ~18" deep at the ground, near some rocks. This slope had an unusually shallow snowpack.

This avalanche ran on Friday (3/15) near Big Sky. It was probably triggered by a cornice fall during warm temperatures late in the day. Photo: E. Howard
