Ski resorts are following the lead of the cruise industry and shuttering dozens of North America’s most popular resorts amid the coronavirus outbreak.

Industry leaders Vail Resorts Alterra Mountain Company decided late Saturday they would close 90 of North America’s most popular resorts, an abrupt about face after vowing previously to remain open during the crisis but take steps to prevent the virus’ spread.

Vail Resorts announced it would shut down its 58 resorts for a week before reassessing, while Alterra closed 40 resorts indefinitely. The Telluride Ski Resort in Colorado and the Aspen Skiing Company followed suit Saturday night.

The announcements came amid an executive order from Colorado Gov. Jared Polis requiring all of the state’s ski resorts to close

“Colorado is strong and we will get through this together. The safety and health of our most vulnerable and of our communities is our top importance,” Polis said. “Everyone must do their part in stopping the spread of this virus. The slopes will still be there when this is all over.”

Colorado has confirmed cases of coronavirus and one death as of Sunday afternoon, according to Johns Hopkins data .

Vail’s resorts include Vail, Keystone and Breckenridge in Colorado; Park City Mountain Resort in Utah; Heavenly, Northstar and Kirkwood in the Lake Tahoe area of ​​California and Nevada; Stowe Mountain in Vermont; and Whistler Blackcomb in British Columbia, Canada.

Alterra’s include Steamboat and Winter Park in Colorado; Squaw Valley, Mammoth and Big Bear Mountain in California; Crystal Mountain in Washington; Stratton and Sugarbush in Vermont; and Deer Valley and Solitude in Utah.

In a news release, Vail Resort CEO Rob Katz acknowledged the short notice for guests already at or on their way to the resorts.
