Route & General Observations

A large slide was noted to have happened in the recent past. The pictures do not do it justice. The slide was very thick with plates of snow. The crown appeared to be two or three feet thick. I placed my sled at the toe to give size reference. The thickness of the slide was at least three feet. It appeared that most of it had slid on top of the thick layer crust I walked through. This was a southwest facing slope. High winds were noted in the area to be from all different directions depending on which valley you were in. Be careful out there!
