Unsure of the exact timing of this and adjacent slides in the drainage. Craig Gordon taught me how to look back at the seven day winds for some of the nearby wx stations and we had sustained winds in the 30 and 40mph range which could have overloaded these slopes. It also looks like some of these large cornices broke-off and triggered these slides that likely had weak snow around the rocks.
This basin faces north/northeast and has a very large open ridgeline to the west where the winds grab lots of snow and transports it onto the lee side of this area.
These adjacent slopes also had lots of debris with the crown line traversing over sub-ridges and gullies.
