About this map

The confluence of major Montana waterways takes center stage in this mid-1960s study of Petroleum County and its neighbors. The landscape is dominated by the Fort Peck Reservoir, where the waters of the Missouri River and Musselshell River meet within the protected expanse of the Charles M Russell National Wildlife Range. The map illustrates the complex shoreline of the reservoir, including the intricate inlets created by Crooked Creek and the namesake Germaine Coulee.

This area, mapped as part of the Department of the Interior program for the development of the Missouri River Basin, reflects a sparsely populated region defined by its hydrography and public land boundaries. The sheet precisely marks the intersection of Petroleum, Phillips, and Garfield counties, following the course of the submerged riverbeds. Steep, eroded coulees like Sherman Coulee characterize the surrounding terrain, showing the transition from upland prairie to the deep river breaks.
