Gilman sits at the northern edge of this agricultural landscape where the borders of Marshall, Jasper, Tama, and Poweshiek counties converge. This 2015 survey reveals a terrain defined by its watercourses and rural burial grounds, reflecting generations of settlement in central Iowa. In the southern reach of the quadrangle, Rock Creek Lake provides a significant hydrological landmark, fed by Rock Cr. The map preserves the locations of several historical cemeteries, including Hickory Grove Cem and Mount Pleasant Cem, which serve as vital points for genealogical research. The settlement of Newburg is positioned along the eastern border, tied to the local road network by routes such as Co HWY t38. The drainage patterns of Big Bear Cr, Sugar Cr, and Brush Cr illustrate the natural topography that has influenced the placement of farmsteads and rural infrastructure throughout the townships.
