Skier Triggered Avalanche in Middle Basin debris

We found this fresh skier triggered avalanche in Middle Basin today 1/5/19. East aspect. 9,400’ elev. It broke 1-2’ deep on weak, sugary facets. We had stable results in our stability tests (so did another group nearby), but this slide and recent reports of collapsing in the area indicate an untrustworthy and unstable, poor snowpack structure.
