1967 Map of Tongue River Dam

About this map

Tongue River Reservoir and the Tongue River Dam dominate the southeastern corner of this 1967 survey of the Big Horn and Rosebud county line. The landscape is defined by an intricate network of drainage systems, including Fourmile Creek in the north and the multi-branched Leaf Rock Creek to the south. This area of Montana reveals a rugged topography of dissected plateaus and deep draws, such as Barber Draw and Post Draw, which highlight the erosional patterns common to the Tongue River basin. Occasional industrial and hydrological markers, such as a Gravel Pit, a Gaging Sta, and a Drill Hole, point to the logistical management of the river and local resources. The map also captures the confluence of smaller tributaries like Monument Creek and Coal Creek as they feed into the primary waterway.
