Cerro Summit (elevation 8,042 feet (2,451 m)) is a mountain pass in the State of Colorado, located about 14 miles east of Montrose, Colorado. It divides the watershed of the Cimmaron River to the east and the Uncompahgre River to the west, both of which eventually flow into the Gunnison River. Although grades on U.S. 50 are gentle, the former rail line over Cerro Summit had a ruling gradient of 4% or 1 in 25 and it was not uncommon for most freight trains to require a banker.
