Poplar Grove and the surrounding rural townships of northern Boone County are defined by a grid of farm-to-market roads and the winding paths of several creeks. The Illinois-Wisconsin border serves as the northern boundary, with the settlement of Bergen situated directly along State Line Rd. The landscape is largely agricultural, punctuated by small crossroads communities like Blaine, Hunter, and Beaverton Crossroads, each maintaining its own distinct local identity.
