Avalanches observed along E facing side of west Jawbone Canyon gully, where steep, rocky and loose terrain released snow. I suspect these avalanches occurred sometime during our 12/24 storm, during the wettest, heaviest part of that storm. Throughout the day the temps dropped to create lighter snow, but chances are the heavy, loose wet snow released before this occurred.
