This was a guided cat-skiing group.
- BC Zone: Aspen
- Area Description: North facing aspect of McFarlane's on Richmond Ridge at 10900'. The run is known as Happy Face.
- Weather Description: Overcast with light-moderate winds out of the SE. S-1 with temps in the mid-high teens.
- Snowpack Description: On a similar slope to what slide, but not actually on the slope that did slide, we observed a fresh 5cm breakable wind slab, but other than that there were no signs of instability. There was only very minor cracking in that wind slab, and it wouldn't move at all off the ski tracks. A crown profile is planned for Saturday 1/3.
- Avalanche Description: SS-AS/u-D2-R2-O. Slide propagated aprox. 200ft across and ran aprox. 700ft downhill. The crown was 12-30" deep. Northeast aspect, 10900' on a 35 degree slope. The person who triggered it was the 5th person to ski the slope, and when he did the fracture propagated aprox 20ft to his left, 20ft uphill, and 100ft+ off to the skiers right. He was carried aprox 400ft and ended up on the surface. He was never submersed in the avalanche, but did get swept through some trees and suffered a knee injury. This was our 6th run in the area, and 3rd on a NE aspect. On those other runs we saw no signs of instability.
