2021 Map of Twelvemile Sink

USGS Topo · Published 2021

About this map

Twelvemile Sink occupies a unique depressions in this high-desert landscape of Sweetwater County, where the topography is defined by significant canyons and a sparse network of access roads. The terrain is marked by the presence of Buckhorn Canyon and Eighteenmile Canyon, which cut through the southwestern portions of the quadrangle. These drainage patterns illustrate the region's arid geomorphology, characterized by deep incisions that funnel toward the sink. Human movement through this remote territory is traced via Eighteen Mile Rd and Monument Butte Rd, which navigate the high ground between the canyons. The map provides a detailed survey of the Public Land Survey System grid, including corners for t24n r109w and t24n r110w, showing how this rugged Wyoming landscape was systematically partitioned for grazing and mineral management in the early twenty-first century.
