More detailed information about the avalanche: 

We spotted this avalanche across the valley from the ridge we were climbing. It is actually 2 separate slides, the one on the left (looking at them) appeared to have about a 3' fracture.

The one on the right was larger, the crown appeared to be 5'-6' at it's tallest point and the slide ran all the way down the gully out of the photo.

This is an area sometimes skied from above, and often times traversed into by people after they come out the bottom of North Bowl,
