 Activity:   Skiing
AVALANCHE OBSERVATIONS
 How Many?  ~10
 Trigger:   Natural, Unknown
 What type of avalanches?   Soft Slab
 What size?
 Size 1: Relatively harmless to people
 Size 2: Could bury, injure, or kill a person
 What Elevation?  6500' to 8500'
 What Aspect?   N, SE, S, SW, NW
 Comments: We observed lots of avalanches that looked to be a day old or so. Some could have released in the last 24-hours. Most avalanches were on southern aspects, but we did notice a number of slides on north aspects. We did not observe any in action. Most of the avalanches were D1 sized and did not run to the valley bottom. One slide on the north side of Patterson Ridge looked to run about 2,000 feet.
MESSAGE
 Comments: The rain line was at 7,000' on the dot. Above that, the snow was dry or windblown. Below 7,000 there is a substantial crust that is strong enough to support a skier walking in boots. Underneath the crust is soft, unsupportive snow. We skied terrain well below 30 degrees on a northern aspect. I did not want to ski any southern aspects or anything steeper than 30 degrees. We traveled one at a time or well-spaced out to minimize risk. Riding conditions are awesome above 7,000'!

Same two slides as before, but from higher up the ridge. Note that they seemed to have failed at the upper/mid snowpack and not the ground.
