The town of Newburg and the southern edge of Gilman anchor this agricultural landscape at the meeting of four counties: Marshall, Jasper, Tama, and Poweshiek. The terrain is defined by the drainage basins of several waterways, including Rock Cr which feeds into the prominent Rock Creek Lake in the southwestern portion of the sheet. Other local streams like Sugar Cr, Big Bear Cr, and Brush Cr create a network of valleys across the prairie, influencing the grid of gravel and secondary roads such as Co HWY t38 and HWY f17 E. For researchers tracing family ties to the area, several local burial grounds are noted, including Green Cem, Hickory Grove Cem, and Mount Pleasant Cem. The presence of these landmarks alongside the lake and the established settlement at Newburg highlights the long-standing community structure of this rural central Iowa region.
