KEYSTONE, Colo. - Ski season in Colorado started Sunday morning.
Arapahoe Basin is the first ski resort to open this year.
Arapahoe Basin opened one run at 8:30 a.m. Sunday thanks to early season snow and snowmaking. That's four days earlier than its opening day last year.
Loveland Ski Resort has also been making snow, but said they will not be opening this weekend.
