The Magic Mile is an aerial chairlift at Timberline Lodge ski area, Mount Hood, Oregon, U.S. It was named for its unique location above the tree line and for its original length. When constructed by Byron Riblet in 1938, it was the longest chairlift in existence, the second in the world to be built as a passenger chairlift, and the first to use metal towers. 〔(【引用サイトリンク】 Magic Mile Sky Ride ) 〕 〔(【引用サイトリンク】 Alpenglow Ski Mountaineering History Project, Compendium of ''Northwest Skier'' Magazine )〕 The chairlift has been replaced twice, in 1962 and 1992. Like its predecessors, the current chairlift loads near the lodge at 5,950 feet (1829 m) and unloads at 7,000 foot (2134 m), up an average gradient of 20%. Except for the very lowest part of the route, the lift is not protected by trees or land features and faces the full force of snow storms. Heavy winds frequently produce huge snowdrifts and copious and dense snow challenge lift crews to keep the lift open. The lift is generally closed when winds exceed 50-60 mph or dense fog reduces visibility below about — in all, about 40% of winter days.〔 == First chairlift, 1938–1962 == Construction of the original Magic Mile began in mid-1938, a few months after Timberline Lodge opened for business with a portable rope tow. (The tow remained in operation for at least several years.) The chairlift was the first built by the Riblet company, which drew heavily on its designs for aerial trams for mining companies. Completed in late 1939, it loaded its first passengers on November 17, 1939, 〔 and was dedicated by the Crown Prince and Princess of Norway〔(【引用サイトリンク】 Great Lodges of the National Parks—Pacific Northwest: Timberline )〕 (later King Olaf). The original chairlift was a ''single'' — each chair held one rider. The ride took 11 minutes and carried 225 passengers per hour. It was as popular a summer tourist attraction then as it is now.〔 The lift line was slightly east of the present chair. The upper bullwheel was inside Silcox Hut, which is 212 m (700 ft) ESE and lower in elevation.〔 The bottom was east of the lodge about 377 m (1236 ft, one quarter mile) ENE at essentially the same elevation as the present chair.〔USGS topographic maps plot the lower station building at without notation. However, photos of the era show the lift line aimed for this area. Also, the small parking lot slightly to the east is sometimes labeled "Magic Mile parking".〕 Timberline Lodge shut down for World War II and struggled financially through the 1940s and early 1950s. Mounting disrepair, vandalism, neglect and unpaid taxes closed it February 17, 1955, at which time the Magic Mile was nonfunctional. The lodge reopened late that year under the management of Richard Kohnstamm, whose family still manages the resort.〔The ski area ''Special Use Permit'' expires May 2022.〕 The Mile was made functional again, and in the following summer, ski racing camps began.〔 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「Magic Mile」の詳細全文を読む スポンサード リンク
