Skiers noted an avalanche on Red Mountain that spanned about 2000’. They estimated it was 1-3’ deep in the newer snow, for the most part, but a portion of it broke 15’+ deep and ran at the ground. Photo: S Reinsel

Across the road from Bacon Rind at 7,070' on a west facing slope I saw a small skier triggered slide that ran into the Gallatin River.

On Buck Ridge today (3/5/23) we found fresh, unstable drifts. This fresh slab was 4-6" deep. Cracking like this is a sign that wind slabs will avalanche on steeper slopes. Photo: GNFAC

From IG: Skiers near Mt. Blackmore on 2/24 saw a large avalanche on the east side of Mt. Blackmore that appeared to have happened in the last 24 hours.

From email 2/24/23: "Came across this very large cornice that appeared to have broken naturally sometime in the past 24 hours. Saw a few others that had broken recently throughout our tour, but none as large as this." E. Heiman
-
From email 2/24/23: "Triggered a small 2’ deep wind slab in new snow this afternoon. NNE aspect 9,500’, approximately 38° slope. Riding was excellent on all high North facing slopes and this was the only sign of instability we saw all day. Wind was howling on the way out, lots of snow coming out of the trees and transporting at ridge tops."

"Seemed to be a decent sized slide runoff was pretty deep where it stopped in the trees figured it was probably two days old. Southwest facing. Roughly 44.86695° N, 111.24123° W"

From obs: "This afternoon my group of 4 was riding up out of Tepee Creek heading towards Cabin Creek and I set off this small slide on a northeast facing slope as I was coming down it. The slide broke about a foot deep on top of the packed layer of snow and was 150-200' wide at the crown. Thankfully it slid slowly, less than 100' and I was able to ride out of it. '

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."

On a Jan. 16 tour into Beehive, we found the concerning layer of feathery surface hoar buried under 6" of snow. It is widespread from Big Sky through West Yellowstone and Cooke City. It has produced avalanches near Hebgen Lake, with more snow, it will likely produce avalanches in Beehive too. Photo: GNFAC

Darren Johnson was a passionate skier, patroller, and wildland firefighter and this fund helps his memory live on. During the week of January 16, 2023, there are two events happening to help spread awareness about the DJ Fund and generate donations for the next recipients to attend National Avalanche School in October 2024. The first event is at the Independent Theatre on Tuesday, January 17. This charity event has a $10 entry fee which includes a raffle ticket to a silent auction. On Thursday, January 19, join us at Beehive Basin Brewery for a raffle and pint night in which $1 from every pint sold goes into the DJ Memorial Fund.
To donate to the Darren Johnson Avalanche Education Memorial Fund visit djmemorialfund.org, or join us at these two exciting events hosted by Yellowstone Club Ski Patrol. Huge thanks to all who have sponsored and donated to these events.

Skier unintentionally triggered and was caught in wind slab avalanche on the Y couloir in Sheep Creek Drainage. Skier was carried 10m before self arresting. The slide ran ~250m down and broke across the entire width of the couloir. There were no injuries and skied away.
