1965 Map of Locke Ranch

About this map

Fort Peck Reservoir dominates the center of this 1960s landscape, marking the flooded channel of the Missouri River as it winds through central Montana. The map illustrates a transitional period for the Charles M. Russell National Wildlife Range, showing the intersection of managed federal lands and private holdings like Locke Ranch. The terrain is defined by dramatic elevation changes where the plateau of Hawley Flat drops into deeply eroded drainages such as Coburn Coulee and Dam Coulee. Isolated infrastructure, including Legg Well and remote Landing Strips, points to the region's reliance on aviation and livestock ranching. The boundary between Phillips Co and Petroleum Co bisects the reservoir, while named points like West Bend and Jim Bend provide navigation markers along the vast shoreline.
