Fun Facts about The Legend! Arapahoe Basin Ski Area opened to the public in 1946 with one, mid-mountain rope tow that skiers reached in an Army weapons carrier pulled by a four-wheel drive vehicle. A-Basin reported 1,200 skier visits. They paid $1.25 a day to access the mountain. It wasn't until the 1947-1948 season that chairlifts were installed. Arapahoe Basin's first chairlifts were the 1st post-war chairlifts ordered in Colorado. Those chairlifts must have made quite the difference. Skier visits jumped over 1,000% from the 1st to 2nd season to 13,000. With a base of close to 11,000, and a summit elevation more than 13,000! Arapahoe Basin Ski Area has the highest skiable terrain in North America and a vertical drop of 2,270'. Opening in late October and not closing until June, Arapahoe Basin also boasts one of the longest seasons in North America. Our 960 exhilarating acres does not include the legendary East Wall, which has 90-110 acres that we don't even count. How's that for a terrain bonus! Arapahoe Basin's Treeline terrain park is one of the highest elevation terrain parks in North America and stays open until June of each year. The Treeline use to be called the Mutha' Hucker. The Pallavicini run and lift are named after a similarly shaped nose called the Pallavicini Couloir on Grossglockner, the highest peak in Austria (12,457 ft.), first climbed (in winter, no less) by the Austrian mountaineer, Count Pallavicini. In 1974 the ski area sold a lift ticket for $7.50. A three day pass was $18 and a season pass was $125. The current A-Frame lodge in the base area was once a missile testing facility.
