Got some better photos today...
First photo below of starting zone and crown is from Jeff Metzger.
More starting zone photos.
Photos of toe of debris - looks like a nice (20' deep?) pile of debris at the toe.
Google Earth Image showing the general path. I couldn't see the East facing terrain real well, but it looks like a couple of other smaller paths contributed snow to the debris pile. These looked to be mostly wet loose slides, but fairly large.
