General Comments 2

video of a rider in the party hillclimbing next to yesterday's climax avalanche. all the riders had beacons, rescue gear, airbags or avalungs and knew the territory well. Most had taken some sort of avalanche class.

He was partially buried, along with his sled, down at the toe of the debris - not far from the looker's left sapling. An expert rider with a top of the line sled, he said he triggers and is caught about once a year. - Including a large one in last year's 10,420' slide.

General Comments 3

A good shot of the size of the blocks. Hard slab was 18"-7' deep. Pencil plus hard slab over 2-3mm facets and depth hoar.

General Comments 4

Once again, the internal strength of the hard slab pulls way, way back onto the ridgeline.
