Thunder Basin National Grassland dominates this high-plains landscape in Converse County, where the topography is defined by the ephemeral drainage systems of the Powder River Basin. The Dry Fork Cheyenne River winds across the central sections, joined by tributaries such as Dugout Cr and the descriptively named Calamity Gulch. This 2021 survey illustrates a region shaped by modern conservation and land management, with much of the terrain designated as national grassland. Sparse human infrastructure is limited to the occasional rural corridor like Co Rd 40 and the Phillips Draw Trl, reflecting the open, pastoral nature of the Wyoming interior. Survey boundaries for t39n r71w and t38n r70w delineate the vast tracts of public and private land typical of this cattle-country frontier.
