22-23

From 4/11/23: Yesterday (4/10) Colters released a wet slide (approx 1-3pm) that filled the top of the wiggle and left debris 300ft past the south bowl traverse.

Today Stupor had a similar sized release just after noon.

The best noted natural release was a wet slab release on the southern edge of the football field that put a pile of debris below the cave.

Wet Slide off Bridger Ridge near Baldy

Notes

While descending from a trail “run” (definitely more of a post hole) up towards Baldy, I saw a medium-sized wet slide on the eastern side of the ridge underneath some large rocks. The slide was roughly 15-20’ across at the portion I could see and traveled several hundred feet down the mountain. I could hear trees snapping (sadly in the video I don’t think you can, as my breathing is way too loud) and watched the avalanche move for almost a minute. I was very thankful for my careful route finding and avoidance of steep slopes!

Notes

There were maybe 6-10 D1.5-D2 wet loose slides scattered around the area that we could see, similar to attached picture of Crown Butte (We could see Miller Mtn. east and north, Scotch Bonnet, Henderson, Crown Butte, Abundance, Wolverine). At lower elevations where the snowpack is shallower, closer to silver gate and the northeast corner of the park, there were some deeper wet loose slides (D2) and a couple small wet slabs (photo). I would estimate most of these happened yesterday (4/10).
