We summited millville peak and arrived to white out conditions and a stiff SE wind, loading the lee side of the ridge heavily. We expected weak cornice formations so we stayed well off the ridge. As we descended along the ridge from millville peak towards the entrance of the dog leg we remotely triggered some huge cornice falls (the size of VW busses and bigger) from about 40 feet away from the cornice/ridge. We were having second thoughts about now but continued on to check out the entrance to our intended line. As we approached the entrance to the dog leg to have a look we remotely triggered a 2-4 deep hard slab that ran down into the thick trees and out of site, leaving car sized chunks of cornice and windslab near the crown. We backed off our line and hiked back out to a safer less wind loaded line back down.

The first photo shows the remotely triggered cornice fall. The next two are of the hard slab.

The hard slab ran on facets above the old rain crust from mid january. We did not investigate the length of the slide. We bailed out to a safer descent and called it a day.

The Avalanche on the Dog Leg was likely bigger than 50 ft.. I just didn't have a good (and safe) vantage point to see exactly how wide it really was and how far it ran. The wind was driving and visibility was poor up there. I would have had to walk under an overhanging cornice to get a good look so i decided against it. It was remotely triggered from the ridge as I walked towards the entrance to have a look into the line. So it broke about 10 feet in front of me.
