Chalk Butte stands as a prominent landmark in this high-desert landscape within Sweetwater County, marking a terrain defined by subtle elevation changes and sparse water features. This early 21st-century survey by the U.S. Geological Survey illustrates a remote ranching or resource corridor where infrastructure is limited to a handful of unpaved routes. Long-established tracks such as Bar X Rd and Luman Rd provide the primary access through the region, reflecting the vast, open-space character of the Wyoming interior. The map also identifies Cord-4-20, a county road designation that speaks to the localized network of Sweetwater County's rural management. For the researcher or land historian, this sheet documents the precise locations of small ephemeral water bodies and the specific paths of back-country roads that support the local livestock or energy industries of the region.
