1967 Map of Grassy Mtn

USGS Topo · Published 1971

About this map

The high desert terrain of Malheur County is defined by the winding course of the Owyhee River and the prominent heights of Grassy Mountain. This 1967 field-checked survey reveals a landscape shaped by water management and ranching, evidenced by the scattered network of reservoirs and springs like Grassy Mtn Reservoir, Schueler Reservoir, and Lone Willow Spring. The eastern edge of the quadrangle follows the river near Lake Owyhee, where dashed blue patterns indicate areas subject to controlled inundation. Remote outposts and geographic markers such as Prospect and Government Corral Spring provide rare points of human activity amidst the complex drainage systems of Sand Hollow and Sagebrush Gulch.
