After descending Beartrap Aspens my partner and I were riding next to the skintrack that goes up the bottom of Beartrap. At one point there is a small, short, but steep slope above the skintrack. My partner triggered the initial slide, but had easily outrun it. As I looked at what just came down another group skiied up behind us and subseqently set the rest of the slide off (an additional 10' accross). Slide was far too small to have carried or buried anyone, but is of note. Crown was 3-5" deep, about 25' accross slid maybe 20 feet.
