Walker serves as the primary hub of this agricultural region where the borders of Buchanan, Benton, and Linn Counties converge. The landscape is defined by the winding course of the Wapsipinicon River in the northeast and several small tributaries including Sand Creek, Blue Creek, and Smith Creek. The town of Rowley sits in the northwest corner, while the small settlement of Spencers Grove is positioned further south, providing a detailed look at the rural township structures of Homer, Cono, Polk, and Grant during the early 1970s.
