Montana, United States
Lost Trail Powder Mountain is an alpine ski area located along the Montana-Idaho border at the junction of US Highway 93 and Montana State Highway 43 at Lost Trail Pass, about one mile northwest of Chief Joseph Pass, which is on the Continental Divide.
The summit elevation of Saddle Mountain is 8200 feet (2500 m) above sea level with a vertical drop of 1800 feet (550 m). The main base area, including the parking lot and lodge, are at 7000 feet (2135 m) and are in Montana, as are the majority of the runs. Chairlift #1 is approximately the Idaho-Montana border; the terrain to the south of it, including Chairlift #2, is in Idaho.
Until 2003, the top of Chair # 1 & Chair #2 was the summit of the area, at 7800 ft. (2377 m), and the vertical drop was 1200 ft (366 m). When chairlift #3 (Huckleberry) was added on the Montana side in 2002, it lowered the base by 200 vertical feet (61 m). The addition of Chair #4 on Saddle Mountain, which opened in February 2003 after delays, increased the area's vertical drop by 400 feet (122 m). The slopes on the mountain are primarily east-facing.
The ski area is known for high snow accumulations but is primarily a day area, used mainly by local residents.
