Yellowstone NP Terrace Mountain

Not sure if this is in your range, but we went to Yellowstone NP - Mammoth Hot Springs and skied off the end of the closed road up towards Terrace Mountain, peaking at 7600 feet. A lot of "cracking" of pieces of grouped snow together while skinning up, about 3-4 inches thick. Kept to very low-angle terrain and skiing down kept hearing a small whoomping from all directions - very disconcerting. Nothing slid (super low-angle terrain) but the snow was pretty soft - except towards 7000 feet and below where coverage was a little thin and rocks become the concern.

One picture I grabbed while skiing down, looks like a big clump that wants to break off if it were steeper. I have attached it.
