2012 Map of Mercer Draw

About this map

Mercer Draw characterizes this stretch of the Wyoming high plains, where a network of ephemeral drainage systems carves through the Niobrara County landscape. The geography is defined by the convergence of several major creek beds, including the wide path of Lightning Cr and its tributaries such as Twentymile Cr and Walker Cr. This area remains largely open rangeland, with its human presence marked primarily by utility and access corridors like Lightning Creek Rd and K Field Rd. The map illustrates the specialized hydrological patterns of the western Great Plains, where water courses like Little Cow Cr dictate the layout of local ranch roads and land use. The absence of concentrated settlements highlights the sparse, rural nature of this portion of Wyoming in the early 21st century.
