The Plum River and its various branches, including the Muddy Plum River and E Plum River, define the undulating landscape of this border region between Jo Daviess and Carroll counties. The rural settlement pattern is anchored by the small communities of Pleasant Valley and Polsgrove, while the northwestern corner is occupied by Massbach. This terrain is characterized by a dense network of local roads following the drainage of Camp Cr and Scrub Cr, highlighting the area's agricultural heritage and the persistence of historic pathways like the Old Galena Trl.
