The latest major storm to hit western North America has taken the deepest reported snowpack in the world through the 3 metres (10 feet) mark.
Mammoth Mountain now reports 343cm (11.5 feet) of snow at the top of its slopes. Three other resorts on America's West Coast are past 2 metres, Mt Baker in Washington State (which holds the world record for the most ever snowfall in a season) on 231cm, Northstar at Tahoe on 226cm and Mt Hood Meadows in Oregon on 203cm.
A statement from Mammoth on Monday said, "The storm is now easing, extensive avalanche mitigation work will take place across the mountain today as our team works to safely reopen terrain after 2.5-3.5 feet of snow in the last 2 days."
The Palisades ski area reported they are at 125% of their average snowpack for December, and as of Monday morning had already seen 9+ feet of new snow since December 1st.
"With all this new snow, we have literally been digging ourselves out for the past few days. Now, with a few dry days in the forecast and a great base of snow, we are turning our attention to terrain expansion," a resort statement explains.
Further inland, ski areas in the Rockies have been reporting several feet of fresh snowfall in the past few days too and Alta in Utah has the deepest snow depth reported there at 196cm.
