The timing of the avalanche is unknown. I chose 3/27 since that day was the peak of instability for wet slab avalanches. The weak layer is unknown, it could be facets, or it could be a density change with meltwater pooling on a hard crust.

The crown is marked with a red line and the black arrow points to the debris pile.
