About this map

Somerville Flats and the Kinney Divide define this portion of the Powder River Basin along the boundary of Johnson and Campbell Counties. The terrain is a complex network of seasonal drainages, where the Powder River cuts through the southwestern corner of the quadrangle. Significant watercourses such as Barber Cr and various named draws—including Windmill Draw, Williams Draw, and Livingston Draw—illustrate the intricate erosion patterns characteristic of this high plains environment.

Evidence of ranching and land management is visible through the naming of these specific draws and flats. The map provides a detailed view of the section lines and township boundaries, such as t50n r77w, which are essential for tracing historical land patents and grazing allotments. This landscape, primarily defined by its hydrology and topographical divides, remains a sparsely settled region of northeastern Wyoming where water access dictates land usage.
