1990 Map of Cow Valley East

USGS Topo · Published 1990

About this map

Malheur Reservoir dominates the northern landscape of this Malheur County region, where the high desert terrain transitions into the broad expanse of Cow Valley. The map reveals a land defined by its water sources and topography, from the drainage of Cottonwood Creek and Willow Creek to prominent elevations like Cow Valley Butte and Brogan Hill Summit. Though primarily an open landscape, human activity is evident through specific infrastructure such as a Radio Tower, a Quarry, and a Corral, indicating the area's utility for ranching and resource extraction. The network of unimproved roads and trails connects these points of interest, tracing the natural contours between Reservoir Butte and the winding course of Jeff Davis Creek. This 1990 edition, based on 1985 aerial photography, provides a detailed look at the rural character of eastern Oregon before more modern developments.
