Bear Trap glades - generally very safe but there is the open steep area above the aspen glades. This avalanche occurred right at the top of the glades where the slope steepens from the summit and the debris ran into the glades. Slide may have been triggered by skiers - it was hard to tell as the previous tracks were filled in. The wind was 35mph+ from the South and cross-loading the slope. Plenty of collapsing/cracking on the way up and snowing 1"/hour the whole time. Tough trail-breaking.
