New Snow

Same

Remotely triggered numerous avalanches on facets beneath new snow of last few days as well as a few isolated pockets to the ground. This facet layer, about 15" down is obviously very weak, widespread, and capable of producing very wide avalanches. Avalanches triggered in this layer have potential to step down to the weak snow at the ground particularly on northwest through northeast slopes above about 8000ft. The Park City area, although sustained less of load then the cottonwoods, has much weaker snow at the ground on northerlies above 8000ft. We found minimal instabilities in the new snow. Storm snow instabilities have settled out and the new snow is well bonded and makes a great slab. We observed some older filled in crowns from natural cycle, yesterday or last night. We experienced thunderous collapses all day.

Persistent Weak Layer

Decreasing Danger

Wind slabs were isolated and not widespread. The strong NW winds have not effectively loaded many slopes. Large ridgetop easterly start zones also had minimal cornices. We did trigger one very wide avalanche on a southeasterly facing slope due to heavy windloading. This was at about 8800 ft on a subridge that had many trees on the windward side that helped to decelerate and deposit wind blown snow. In other words this was not the norm.
