About this map

Dunbar Slough dominates the northwestern corner of this agricultural landscape in Greene County, reflecting the complex water management history of the Iowa prairie. The terrain is defined by a grid of rural roads such as 260th St and 300th St, which trace the section lines established by the Public Land Survey System. Intersecting this rigid human geometry are the meandering courses of Willow Cr and Greenbrier Cr. The engineering of the land for cultivation is most evident in features like Drainage Ditch Number 117, a critical component for draining the fertile lowlands. Spanning four townships, including t83n r32w and t82n r31w, the area remains a quintessential example of the modern Midwestern grain belt, where natural wetlands and technological water control exist side-by-side.
