About this map

The Powder River carves a winding path through the high plains of Johnson County in this 21st-century survey, defining the character of a terrain shaped by deep drainage systems. The landscape is characterized by expansive, level plateaus including Bowman Flat, Culp Flat, and Ricketts Flat, which stand as prominent topographic features between the river and its many tributaries.

Hydrological details are central to this map, showing how secondary seasonal waters like Beaver Cr, Fourmile Cr, and Pumpkin Cr feed into the main river valley. A complex network of erosional features defines the local geography, with named drainages such as Culp Draw, Hupp Draw, Red Draw, and Hynes Draw cutting through the arid landscape. These features reveal the intricate drainage patterns that have historically dictated movement and land use in this part of Wyoming.
