2015 Map of Twelvemile Well

About this map

The Continental Divide traverses the high desert landscape of Sweetwater County in this modern survey, marking a significant hydrologic boundary through a region of arid flats and deep draws. Water access is critical in this environment, anchored by the namesake Twelvemile Well and the seasonal drainages of Tenmile Draw and Dugout Draw. The terrain is characterized by broad expanses like Tenmile Flat, where sparse vegetation and elevation changes define the local geography. Human passage through this section of the Great Divide Basin is traced by a network of rural routes, including Black Rock Connector Rd and Black Rock Flat Rd, which connect isolated wells and ranching infrastructure. This document provides a clear look at the public land survey system divisions across Township 21 and 22 North, reflecting the enduring grid-based management of the Wyoming interior.
