1986 Map of Crowley Dam

USGS Topo · Published 1986

About this map

Crowley Dam sits at the heart of this dry Montana landscape, a focal point for water management in an area defined by seasonal drainages and topographic shifts. The terrain is marked by the winding path of Alkali Creek and the deep incisions of Howard Coulee, reflecting a landscape shaped by intermittent water flow and erosion. Mapping efforts by the Geological Survey during the late 1970s and 1980s illustrate the sparsely settled nature of the region, where a solitary Well is one of the few indicators of human infrastructure. The boundary between Petroleum Co and Musselshell Co cuts across the southern portion of the sheet, providing a clear reference for researchers and local historians tracing regional property and administrative lines in this open country.
