Polk City sits at the heart of this landscape, positioned between the expansive waters of Big Creek Lake and Saylorville Lake. The area is defined by its recreation-oriented infrastructure and evolving transportation networks, with the High Trestle Trl and Neal Smith Trl crossing through territory once shaped by agriculture and rail. To the north, the small settlements of Slater, Sheldahl, and Alleman anchor the tri-county border area where Boone Co, Story Co, and Polk Co meet.
