This was triggered from the ridge and the failure started in the early-Dec layer down 120 cm but subsequently stepped down to the basal weakness. The resulting crown was 2-3 m deep and the avalanche ran about 1 km to the valley bottom. While this was not in the South Rockies region, it provides an example of what might be possible with the weak layers deep in the snowpack.

Smaller storm slab avalanches also have the potential to step down to deeper layers resulting in very large avalanches.
