Lookout Pass is a ski area in northern Idaho on the Montana border, 4 miles (7 km) east of Mullan on Interstate 90. It has a summit elevation of 5650 feet (1722 m) on Runt Mountain with a vertical drop of 1150 feet (350 m) on the northeast-facing slopes. New terrain was opened on the Montana side of the border in December 2003. There are two chairlifts and a rope tow at the area, whose average annual snowfall exceeds 350 inches (889 cm). Lookout Pass is considered the eastern boundary of Idaho's Silver Valley. Additional expansion on the Montana side is scheduled for 2006.
