Thunder Basin National Grassland dominates this high plains landscape, where the drainage systems of the Dry Fork Cheyenne River and Lake Cr carve a network of intricate coulees and draws. The terrain is defined by its arid hydrology, featuring named landmarks such as Reed Reservoir and the namesake Tin Can Lake. This area of Converse County illustrates the vast open-range character of eastern Wyoming, where human presence is marked primarily by sparse ranch roads like Dull Center Rd and section-line tracks. The naming of numerous ephemeral watercourses, including Federer Draw and Bruce Draw, points to the importance of water management and topogeography in this ranching environment. This map provides a clear view of the complex land divisions and topography within the national grassland before the most recent developments in the region.
