Just one of over a dozen sled triggered slides form the last few days.
Pit dug adjacent to upper right flank of sled triggered slide from 2/5. Judging from tracks and foot prints, its likely that the second rider on the slope triggered the slide from the apex of the high mark and jumped off of the slab sending the sled for the ride. Close one. Weak layer was a thin layer of NSF that formed from low density snow that fell around Jan 28. This sat on a slick bed surface of rime crust.

Details unclear and incident unreported. Looks like a rider was caught and lost his sled in this avalanche. At least a set of tracks entering avalanche, near the right flank of the crown, and foot tracks down the bed surface on the right flank leading to apparently caried sled. Several other fresh sled tracks noted on the debris as well.
