Skiers visit Sljeme, which has four ski-runs, three ski-lifts and a chairlift. Poma's first two-seater fixed grip chairlift was constructed in 1958. The Gunbarrel Express is a detachable quad chairlift in Thredbo. The chairlift from River Run was purchased by Eldora Mountain Resort in Colorado. The Tianmenshan Temple is located on the summit, with chairlift or footpath access. The Gunnar Express Lift was constructed in place of the Gunnar Triple Chairlift. The first UNI-GS chairlift, Panorama, debuted in 2003 at Gunstock Mountain Resort. The chairlift and incline railway also required constant maintenance and repair. This lift ran until 1953 when a single chairlift was added in the fall. A chairlift and chalet opened in December 1961. It is 9 kilometres from Charlotte Pass, or 6 kilometres from the Thredbo chairlift. Europe's first detachable 6-seater chairlift 'Tour' was built in Avoriaz. It runs alongside the Screaming Eagle chairlift. It was the second such chairlift in the United States, after Sun Valley. The significance of "detachable" chairlift technology is primarily the speed and capacity.
