Copper Mountain is a mountain and ski resort located in Summit County, Colorado, about west of Denver on Interstate 70. The resort has of in-bounds terrain under lease from the U.S. Forest Service, White River National Forest, Dillon Ranger District. It is operated by POWDR. History The resort opened in November 1972. The mountain has been operated by several owners. In 1980, it was acquired by Apex Oil Company, who operated the area until 1988, when it was acquired by the Toronto-based Horsham Corporation. In 1997, it was acquired by Intrawest, owner and operator of Whistler and operator of Winter Park. Then, in December 2009, Interwest sold Copper Mountain's operations to POWDR. Copper Mountain hosted the World Cup tour in 1976 with four alpine ski races: slalom and giant slalom for both men and women. Copper was a late-season replacement for Heavenly Valley in California, which was low on snow. Rosi Mittermaier of West Germany won both women's races and wrapped up the 1976 overall and slalom titles, and Copper named Rosi's Run after her that same weekend. The mountain is the starting point of the Colorado's Copper Triangle, a road-cycling circuit that has been the home of the annual Colorado Cyclist Copper Triangle Alpine Cycling Classic since 2005. This event benefits the Davis Phinney Foundation. Copper Mountain received its first detachable chairlift in 1986 when Poma constructed the American Flyer lift, a high speed quad running from Center Village to the summit of the I-lift. It received a companion lift in 1989 when Poma constructed the American Eagle lift, replacing the F-lift from Center Village to Solitude Station. The F-lift would later reappear at Big Sky Resort as the Southern Comfort lift, and now operates on Lone Peak as the Dakota lift. The resort's third high speed quad came in 1994, when Doppelmayr USA constructed the Timberline Express to replace the I and J double chairlifts, servicing a pod of blue trails west of the American Flyer lift. The I and J lifts were reinstalled in 1995 and 1996 to provide lift service in the Copper Bowl area, as the Mountain Chief and Blackjack lifts. In 1998, Poma returned to construct two detachable chairlifts for the east mountain. The Super Bee, a high speed six pack, replaced the B-1 and B-2 double chairlifts, providing a one-seat ride from East Village to Resolution Bowl. A short high speed quad known
