2017 Map of Bowman Flat

About this map

The Powder River meanders through the heart of this Johnson County landscape, carving a complex network of drainage systems across the high plains of north-central Wyoming. Named for the silt and volcanic ash along its banks, the river is the central artery for this territory, joined by tributaries such as Beaver Cr, Fourmile Cr, and Pumpkin Cr. The map reveals a series of named plateaus and topographical depressions that define local land use and navigation in this ranching country. Elevated areas like Bowman Flat, Culp Flat, and Ricketts Flat offer level ground amidst the broken terrain, while a series of deep cuts, including Culp Draw, Hupp Draw, and Red Draw, illustrate the erosive power of seasonal runoff in the Powder River Basin.
