1961 Map of Rocky Reef

About this map

The Missouri River snakes through the northwest corner of this terrain, where the Great Northern rail line follows the water's edge near Tintinger Slough. The landscape transitions sharply from the irrigated lowlands of Chestnut Valley to the dramatic verticality of Rocky Reef and Harris Mountain. Evidence of early agricultural infrastructure is clear in the Chestnut Valley Canal, which skirts the base of the rising foothills. Local history is anchored by the Chestnut Valley Cem situated along Millegan Road in the north. Further south, the map details a complex network of drainage systems including North Fork Sheep Creek, Bird Creek, and Sawmill Creek, illustrating how the high-country runoff feeds the valley floor. A solitary Landing Strip and a Gravel Pit near the river highlight the area's mid-century transportation and local industry.
