Rock Creek Lake dominates the southwestern corner of this Jasper and Marshall County landscape, where the waters of Rock Creek are impounded within a valley of agricultural fields. The settlement of Newburg sits centrally along the eastern border, positioned near the headwaters of Big Bear Creek. To the north, Gilman serves as a primary hub for the surrounding rural townships, connected by a network of gravel and paved roads such as Hwy T38 N and Hwy F17 E.
