Natural Avalanches in the Bridgers

Toured up the ramp and north towards hourglass couloir right after heavy snowfall at Bridger. Observed presumably natural wind slab avalanche crown at top of Hourglass (picture). Broke roughly 200ft wide and rather shallow, did not manage to run fully into the apron. Also noted many other small natural avalanches almost all breaking right at the top of the ridge. Strong winds from west loading slopes. Followed some solo tracks down just skiers left of hourglass, noted some instability but no major propagation or slides while skiing. Storm slab not quite cohesive this evening, but could definitely see it getting pretty spooky tomorrow.
