Today is opening day for skiing and snowboarding at Arizona Snowbowl. If you haven’t bought ski passes for today and Saturday, well you are out of luck. Snowbowl officials say they are sold out until Sunday. However, some tickets could be released today and tomorrow, so check Snowbowl’s ticket calendar for updates. The Grand Canyon Express lift will be open from 9 a.m. until 4 p.m., with Midway Catwalk, Logjam, Wild Turkey and Round Up trails open. All regular lift tickets must be purchased online and masks will be required for all guests and employees in base areas, lift lines and inside lodges. For more information, log onto Snowbowl.ski.
