About this map

Thunder Basin National Grassland dominates this high-plains landscape in Wyoming, where a complex network of draws and ephemeral creeks defines the eastern drainage patterns of the Powder River Basin. The terrain is punctuated by significant landmarks like the Cow Creek Buttes, which are accessible via a dedicated trail system including the Cow Creek Buttes Trl and its western and southern counterparts. The map records the early 21st-century character of this open range, where natural features like Split Hill and Cake Hill rise above the surrounding Downs Country.

Water management and drainage are central to the geography here, with Lightning Cr, Little Cow Cr, and Piney Cr carving through the landscape alongside numerous named draws like John Henry Draw and Willow Draw. The interface of public lands is clearly marked along the Converse Co Niobrara Co line, providing an essential reference for land management and history in a region where remote rangeland remains the primary feature.
