Rye Grass Coulee and McCoy Canyon carve through this section of Franklin County, defining a landscape of agricultural plateaus and drainage systems. This 2013 survey reveals the persistent imprint of the Public Land Survey System, with township and range lines like t11n r32e guiding the rectilinear road network across the undulating terrain. The central Rye Grass Flat serves as a focal point for the surrounding rural infrastructure, where local routes such as Rybzinski Rd and Gertler Rd intersect to connect the scattered farmsteads. The lack of concentrated urban development highlights the area's continued reliance on large-scale land use and local access roads like Haverland Koontz Rd, which navigate the elevation changes between the coulee floor and the higher ridges.
