Observed collapsing and shooting cracks near top of meadows around 7700 feet. Dug a pit in this area as well. Snow was 80 cm deep. Our test yielded unstable results - ECTP 11 35cm down on the obvious surgery facets. Slab seemed to be stiffening with warmer temps.

Notes

Starting at  45°11'13.26"N /  111°27'36.92"W, the NNE slope slid  (likely rider caused 2 days ago).
The adjacent slopes at  45°11'18.09"N / 111°27'54.78"W further west were slightly newer perhaps the 26th or late on the 25th. Each ripped down to the ground at the crown. Severe instability was present even when cresting over the slope from the entrance through the regular access to cedar - still not broke open.
