1968 Map of Twelvemile Sink

USGS Topo · Published 1971

About this map

Twelvemile Sink dominates the southeastern topography of this high desert terrain in Sweetwater County. The 1968 landscape is defined by the deep incisions of Eighteenmile Canyon, Twelvemile Canyon, and Buckhorn Canyon, which carve through the arid plateau. Human presence is sparse, centered primarily on transportation and vital water access points. The Lincoln Sweetwater Road and Monument Butte Road provide the primary routes through this remote area, while isolated infrastructure such as the Eighteenmile Well, a Flowing Well, and a Drill Hole point to the critical importance of sub-surface resources and early land management in the Wyoming backcountry. The map captures a moment in the late 1960s before modern developments, showing the raw drainage patterns and elevations of the Great Divide Basin vicinity.
