Shooting cracks in windslabs, Hyalite
From an email:
"At about 9,000ft on the northern aspect of Overlook mtn we dug a pit to the ground (90cm) and got ECTX and very stable results. We found the basal faucets to be quite rounded except for some large ones growing off rocks. About 500ft higher we found a pervasive wind slab that stretched across the face. We got some large shooting cracks while skinning and ended up turning around. Picture is attached. Before the wind picked up we found surface hoar almost 3/4 of an inch deep!

From obs: "We took a tour up into the Maid today. A generally stable snowpack in the area, new snow seemed to bond well with the underneath crust layer. We did observe small pinwheels/rollers on steep pitches on southeast aspects, mostly due to the rocks heating up during the day. We also observed sluff buildup on aprons below the shadier and steep northern aspects." Photo: Tommy S.
Toured up to the ridge at Bridger today and traversed into Bridger Gully. At around 8,000' in the trees above the most prominent snowfield, my partner and I observed very small dry sluffs confined to the new snow. Bellow Bridger Gully, my partner was able to release a slide while traversing through rocks above his intended line. This was on an east-southeast aspect at 7,500'. Photo: Cole Oshiro-Leavitt
