1965 Map of Germaine Coulee West

About this map

The confluence of the Missouri River and the Musselshell River anchors this 1965 survey of Petroleum County, Montana. The landscape is dominated by the rising waters of the Fort Peck Reservoir, which has flooded the deep coulees and river valleys of the high plains. Much of the mapped area falls within the Charles M Russell National Wildlife Range, reflecting a period of significant federal land management and environmental conservation in the Missouri River Basin. The topography reveals a dramatic transition from the tablelands down to the water's edge, where features like Germaine Coulee and Sherman Coulee provide natural drainage into the reservoir system. The map also traces the winding path of Crooked Creek as it approaches the main body of the lake, illustrating the intricate shoreline created by the impoundment of these major western waterways.
