I was eating lunch on Canyon Ridge off Blackerby when I observed a natural avalanche on the other side of the bowel. I suspect the avalanche was triggered by wind loaded snow.
On my way up Blackerby ridge, I observed between 10 to 20 centimeters of fresh snow poorly bonded to an icy surface. I occasionally encountered shooting cracks up to three feet long. Test slopes occasionally produced slabs on the new/old snow interface.
I stayed on low angle and heavily wooded terrain as much as possible.
