1952 Map of Yankee Gulch

About this map

Yankee Gulch and the surrounding drainage basins of Rio Blanco County define this 1952 landscape, where the terrain is carved by complex systems like Black Sulphur Creek and Eureka Creek. The area is characterized by high ridges and deep gulches, such as Ryan Gulch and Wagonroad Gulch, which reveal a pattern of seasonal water management and early resource extraction. Human presence is sparse and focused on ranching and geological exploration, evidenced by the Reigie Ranch, Duckett Ranch, and a Shale Test Well.
