Plenty of collapsing indicates that there are still active weak layers in the snowpack.
High temperatures made the snow noticeably heavy below approx 7200ft even though the sun was behind clouds.

NE ridge of Cape Horn N 8400 |
D1 | SS | O-Old Snow | 30cm | N-Natural | Partially drifted in old slide on N face of ridge at 8400ft, I assume it went on 12/7, possibly when wind shifted to S 12/17, but there is no way to be certain. Trigger is also assumed. There were slides of the same size in all similar terrain features along the ridge from 8400ft. |
There were plenty of collapses on the wind stiffened snow on top of the ridge. None of the collapses set off anything on the N side, and even though it looked wind loaded I could not get any cracks in the few wind pillows I could safely access.
Dug a pit on E facing 25deg terrain at 7800ft, 12/7 was there but was not responsive to my tests.
