Keystone History , opens in a new window
When Max Dercum, along with his wife Edna, founded Keystone back in 1970, he knew how much fun it was to slide down snowy mountains on a pair of skis. The feeling was even better with a smile on your face, next to friends and family, in a beautiful spot high above the rest of the world.
Fast forward to today and while the resort has changed, the importance of putting family and fun first remains as strong as ever.
