Relatively low elevation on the private Mount Aire Canyon Road off the "Ranch Exit" in Parley's Canyon. This came off of a northern aspect near "Rabbit Head" for those familiar with signs on the road, and while there were plenty of trees and I couldn't visualize the top of the slide, the slope angle near the road was in the neighborhood of 35°. Avalanche debris was 6 to 8 feet deep across the road, which is not plowed in the winter but is frequented by snow cats, snowmobile's, UTVs with tracks, etc. Several passes had already been made over the top of the debris pile. The photo is taken from above and doesn't do justice to the depth of the debris. Given how dense the trees were and the nature of the terrain, I highly doubt this was human triggered as people typically don't ski that terrain and that low in the canyon. There was approximately 5 inches of new snow on top of the debris pile, suggesting this likely happened a couple of days ago .
