Elk Park Pass


Elk Park Pass, elevation, is a mountain pass on the Continental Divide in southwestern Montana, about northeast of Butte. It is traversed by Interstate 15 and is one of three crossings of the Divide by the Interstate, the others being Monida Pass and Deer Lodge Pass southwest of Butte. Elk Park Pass lies on the border between Silver Bow and Jefferson counties and is remarkable for its highly asymmetrical nature. The approach from the north is through namesake Elk Park, a high, mostly treeless plain, and the grade is almost imperceptible. The elevation at the northeast end of the park, about from the pass, is about, only lower than the pass itself. However, at the south end, the highway drops from the pass into Butte over a distance of only about.
At one time Elk Park Pass was also traversed by a railroad line, constructed by the Great Northern Railway and later operated by its successor, Burlington Northern. However, this line was abandoned in 1972.
