22-23

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."

Large avalanche in Sheep Creek from 2/21: "slide in the photo looked to be an average of about 2-4' deep (6' deep in places) and about 800-1000' wide, spanning across lots of different terrain features.

I also noticed that the main south facing slide path off of Miller Mountain avalanched very large as well. (the same avalanche path where the snowbiker was killed last winter)  I couldn't see the crown, but the debris ran to the valley bottom and appears to have flattened a large stand of mature timber."

There were large slab avalanches that happened on both sides of the valley on 2/21.  Northerly and southerly aspects. Photo: B. Fredlund

From IG message 2/24/23: HS-N-R2.5-D2-O. In emigrant gulch on an east aspect around 9k feet. Seemed to have stepped down on to a PWL, however it’s pretty tough to tell.

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.

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.

I was particularly impressed by the width of one of the slides Nate observed yesterday.  (one of the 2 photos attached).  That slide in the photo looked to be an average of about 2-4' deep (6' deep in places) and about 800-1000' wide, spanning across lots of different terrain features.

I also noticed that the main south facing slide path off of Miller Mountain avalanched very large as well. (the same avalanche path where the snowbiker was killed last winter)  I couldn't see the crown, but the debris ran to the valley bottom and appears to have flattened a large stand of mature timber.

VERY windy out there today.  Primarily SWerly, but blowing in all directions and moving LOTS of snow.  Natural avalanches likely happening today.

As seen from the highway, Lamar Valley, SE aspect. Mid-morning today. -3°.
