Cannon Mountain (formerly Profile Mountain) is a peak in the White Mountains of New Hampshire. It is known for both its technical rock and ice climbing on its cliff face and skiing at Cannon Mountain Ski Area. Until the formation collapsed on May 3, 2003, it was also home to the Old Man of the Mountain. Cannon has three sub-peaks with heights of 3,693, 3,700, and 3,769 feet (1,125, 1,127 and 1,148 m), collectively known as "The Cannon Balls." Geologically, it is an exfoliating granite dome. Part of the Kinsman Range, the mountain is located within Franconia Notch State Park. ==History== Rock climbers were pioneering routes on Cannon's cliffs in the 1920s. Its ski area is one of the oldest in North America. Trails had been cut on the mountain prior to 1933, but the mountain gained widespread recognition that year when the Taft Slalom was cut as the first racing trail in North America. The mountain gained lift service with the construction of the first aerial tramway in North America, in 1938.〔("Tourist to Ride Aerial Tram to Mountain Top" ''Popular Mechanics'', September 1937 )〕 A new tram was erected in 1980 with a vertical ascent of 2,022 feet (616.3 m) and a capacity of 140 people (two seventy-person cabins), roughly three times larger than the original lift. The old tram base and summit-stations remain intact, and one of the old cabins serves as the entranceway to the New England Ski Museum, opened in 1982 at the mountain's base area. The museum houses what it calls "the most extensive collection of historical ski equipment, clothing, film, photographs, literature, and artwork in the East" and is one of four museums in the U.S. to be recognized by the United States Ski Association as a Regional Museum. Cannon hosted the first Alpine Skiing World Cup races ever held in North America in 1967, with races being listed as occurring at Franconia. In 1972, the US Board on Geographic Names officially changed the name from ''Profile Mountain'', which it had been called officially since 1917, to Cannon Mountain.〔 The two names both are derived from natural rock formations featured on the mountain; the former being the famous "Old Man of the Mountain" and the latter being a series of boulders which, when viewed from the foot of the mountain, resemble an antique cannon. Before being called Profile Mountain, the mountain was also called Frank Mountain. On April 2, 1973, the second strongest surface wind gust ever recorded in the United States of America was measured by University of Massachusetts Amherst researchers on the summit. Although wind velocity maxima were measured at , this reading represents the physical limit of the recording instrument, and thus the true value may have been quite higher.〔http://www.mountwashington.org/education/The_Great_Windstorm.pdf "The Great Windstorm of 2 April 1973 on Cannon Mountain, New Hampshire", ''Weatherwise'', vol. 27, no. 4, August 1974〕 Only the record value measured on nearby Mount Washington in 1934 exceeds this value in terms of American wind extrema. The summit of Cannon Mountain is home to a UHF amateur radio repeater on 449.875 MHz as well as two repeaters belonging to the ABC affiliate WMUR-TV. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cannon Mountain (New Hampshire)」の詳細全文を読む スポンサード リンク
