Large Collapses Sheep Creek, Cooke City

From obs: "Probably heard the largest whumph i ever personally heard while skiing near the ridge on the Burn at Sheep Creek. Other groups also reported hearing whumphs too. While skinning out of sheep on a southern aspect we started seeing signs of warming with little pinwheels but none grew big and none were natural."

From another group: "...A few whomps were heard/felt skiing without any propagation or slides on the slope we skied... 
we did talk to the group of 3/4. Earlier in the day, they had skinned further up the drainage and climbed up a  west facing rib of Miller proper. On the first steeper slope while skinning up they experienced large snow settling and bailed."
