Vail was incorporated in 1966, four years after the opening of Vail Ski Resort. The ski area was founded by Pete Seibert and local rancher Earl Eaton in 1962, at the base of Vail Pass. The pass was named after Charles Vail, the highway engineer who routed U.S. Highway 6 through the Eagle Valley in 1940, which eventually became Interstate 70. Seibert, a New England native, served in the U.S. Army's 10th Mountain Division during World War II, which trained at Camp Hale, 14 miles south of Vail between Red Cliff and Leadville. He was wounded in Italy at the Battle of Riva Ridge but went on to become a professional skier after he recovered.
