2/4/23: We dug a pit near the top of our ascent on a west aspect at 9,100'. HS was 160cm and we found surface hoar buried 55cm deep (105cm above ground). It did not propagate or easily break in our tests, but it was a clear stripe in the wall and may have contributed to the adjacent large avalanche last weekend. Photo: GNFAC

Dug at South facing snowpit at 9700' near the base of a wind-loaded slope, ECTX HS:280. Continued on less than 200' up the slope, the skier breaking trail triggered the avalanche. The third skier in the group of five was caught, carried, and buried to the waist. The crown was 1-2' deep, and 50 feet wide. Location: South of Fisher Mountain. Yesterday triggered a small windslab on a north-facing slope on miller ridge, no one was involved.

Avalanche (possibly sled/human triggered) on an easy to northeast facing slope around 9300 feet.  There were lots of sled tracks on the slope, which is located just out of the wilderness at the far end of Buck Ridge.  Slide and sled tracks appeared to be from after the weekend storm and were covered with light snow from the last couple days.  Noted lots of wind transported snow along buck ridge this afternoon.

We triggered this very small slide on a steep convex  rollover by mt abundance. South facing. Triggered from on top by snow bike. Was only 60’ wide and didn’t run far at all. About a foot deep.  Some impressive high mark tracks in the area. No other signs of instability today.

A snowboarder noticed several small slides on the east-facing walls of the Main Fork of Hyalite Creek and a small slab avalanche in the back of the Divide Peak basin. This slide is in an area locally known as Candy land/ ice farm

From Obs: "Went skiing up in Flanders area and saw several avalanches with crowns ranging from 1-3ft deep and running a several hundred yards wide. Also experienced 2 whumphs and some cracks on a wind-loaded aspect near the ridge" Photo: B. Farrell

As we rode into Lionhead we saw many slides that either ran naturally or from cornice falls. Most of the slides happened Fri or Sat. Winds are blowing strong at all aspects and elevations. Slopes are being loaded further and we triggered a small slide (video) from 50 feet away (aka remotely triggered). This is a serious sign of instability and we were careful to not get on or underneath avalanche terrain.
