Haskell Pass, elevation 4300 feet, is a historically significant but now little-used mountain pass in northwestern Montana, between the Flathead and Kootenai River drainages. From 1892 to 1904 it was traversed by the original main line of the Great Northern Railway from Kalispell to Libby. This route was abandoned in favor of a longer but flatter route via the Stillwater, Tobacco, and Kootenai Rivers.
