The Grand River and its numerous tributaries, including Plum Creek and Sun Valley Creek, define the rolling drainage patterns of this Ringgold County landscape. The town of Diagonal serves as the primary hub, where a grid of residential streets like W 3rd St meets the rural road network. Nearby, the smaller settlement of Knowlton sits just north of the town center.
