Irish Creek and its tributary East Irish Creek define the drainage patterns across this section of Ziebach County. The terrain is characterized by the complex dendritic drainage of the Missouri Plateau, where intermittent streams like Red Earth Creek have carved a network of draws and ridges into the landscape. This 2017 survey shows a region almost entirely defined by its natural topography and the Public Land Survey System grid, including boundaries for t16n r21e and t15n r21e. With no major roads or settlements indicated, the map serves as a primary record of the untouched prairie drainage systems that dictate land use and livestock movement in this part of South Dakota.
