Avalanche Forecast

The Utah Avalanche Center's avalanche forecast for the Salt Lake area on Saturday, December 20, says, "You will find Moderate avalanche danger on upper-elevation slopes facing west-southeast. The problem is wind-drifted snow: look for cohesive slabs up to a foot thick beneath exposed ridges. While these wind slabs are dangerous on their own, they are also stressing persistent weak layers. Stick to non-wind-loaded slopes to avoid triggering these overlapping hazards."
