From email on 2/21/20: "...observed today from the highway. It appears like it was probably triggered by a skier yesterday (on Feb. 20).  It was on a south aspect around 8,000', and estimated to be 1-2' deep and about 30' wide." Photo: B. Fredlund

From email on 2/20/2020: "I found some localized instabilities, including some wind whales on the ridge north of Bradley’s... The slide in the photo probably happened naturally this late morning, with a trigger of sun-heated snow from the cliffs above (just west of Texas Hill). It ran approximately 100 meters."

Multiple crowns on Wilson seen from moonlight basin, pictures aren’t good quality and hard to see the crown. Not sure how big the crowns are, but looked like a deep slab. Photo: Tommy Saulnier

"A small slide approx 100 ft wide ran about 40 vertical feet. Crown was 3-4 feet deep. Aspect, SE. Trigger unknown however tracks indicate it was likely a snowmobile trigger." Photo: Reed Youngbar

"I had been riding trees most of the day down low and moved up to about mile marker 10 later in the day. Did a side hill through open trees and stopped on top of this slope. Watched it all propagate and slide below me." Photo: anonymous

From message: "Went out on a recon to Buck Ridge today. Knew the dangers and avoided riding open slopes. I had been riding trees most of the day down low and moved up to about mile marker 10 later in the day. Did a side hill through open trees and stopped on top of this slope. Watched it all propagate and slide below me." Photo: anonymous

We observed an avalanche on a southeast face while touring in the Absorokas. The avalanche appeared to be naturally triggered earlier in the morning as there were no tracks and my partner and I was the only party in the area today. The avalanche appeared to break on the ground, was about 200 feet wide and ran 600 feet. It was the only avalanche we observed today and was on a relatively shallow slope compared to other regions. We had observed widespread whumpfing and collapses throughout the day. Photo: M. Beck

"...picture is a close up of the avalanche on the ridge between Elephant and Blackmore on a south aspect. This one was the largest and the most fresh. All avalanches appeared to be naturally triggered from wind loading." Photo: T. Chingas

"looking at Alex Lowe Peak from the west ridge of Elephant. There were 5 avalanches clearly visible. I highlighted the crowns/debris paths with red." Photo: T. Chingas

"Toured up Blackmore today... Also saw the wheeler mountain avalanches from a few days ago." Photo: Mike Murray
