1984 Map of Last Chance Reservoir

USGS Topo · Published 1984

About this map

Last Chance Reservoir sits at the northern edge of this high-plains landscape in Valley County, where the drainage systems of Deep Creek and Willow Creek define the local topography. This 1984 provisional survey captures a vast expanse of open country characterized by intermittent watercourses and the broad expanse of Wild Horse Flat. The land is marked by the branching headwaters of the West Fork Willow Creek and the winding path of Cow Coulee, illustrating the complex natural irrigation patterns essential to this region of Montana. Lacking significant urban development, the map focuses on the intricate contouring of the coulees and flats, providing a clear record of the area's physical geography and water management features as they existed in the late twentieth century.
