2018 Map of Lost Springs NW

About this map

Twentymile Cr and its tributaries carve a network of drainage basins across this corner of the Wyoming high plains, where the Converse Co Niobrara Co line marks the eastern edge of this landscape. The terrain is defined by its seasonal hydrology, featuring localized landmarks such as Baby Springs Draw, Flat Top Draw, and Dumbell Rock Draw. These features suggest a traditional ranching environment where water sources and topography dictate land use. Transportation is limited to a few arterial routes including Twenty Mile Creek Rd and Co Rd 53, which provide access through the open country. The intricate branching of W Harney Cr and E Fork Twentymile Cr indicates the natural flow patterns that have shaped this region of Converse County for generations.
