1990 Map of Thousand Creek Gorge

About this map

The Sheldon National Wildlife Refuge dominates this high-desert terrain where the Nevada and Oregon state lines meet. This landscape is defined by dramatic elevation changes, from the sheer walls of Thousand Creek Gorge to the broad expanses of Big Spring Table and Jackass Flat. Water sources are critical landmarks in this arid environment, represented by Big Spring and the winding course of Thousand Creek. Human presence is sparse but notable, centered around the Thousand Creek Ranch and Alder Creek Ranch, reflecting the region's enduring ranching heritage. Small-scale industrial activity is evidenced by a Quarry and a Prospect located near the base of McGee Mountain, while the northern edge of the map tracks the remote Harney and Humboldt county boundaries.
