Portage Detroit Ditch defines the low-lying prairie hydrology of this border region, cutting through a landscape of shallow wetlands and seasonal basins. This 2014 survey captures the precise intersection where Dickey Co and Sargent Co in North Dakota meet Brown Co in South Dakota. The survey reveals a strictly rectilinear section-line road system, including routes like 109th Ave SE and 101st St SE, which impose human order on a terrain dominated by glacial depressions. The absence of traditional townsites underscores the rural, agricultural character of this area, where land management revolves around the drainage patterns of the ditch system across the state line.
