About this map

The Blue River and Fennimore Fork carve through this corner of Grant County, defining a landscape of prominent ridges and deep agricultural valleys. The small settlement of Castle Rock sits near the confluence of several coulees, including Clow Valley and Crow Valley Road, serving as a focal point for the surrounding rural homesteads. High above the riverbanks, the Cedar Cliff overlook offers a vantage point over the winding waterways that have shaped the region's geography.

Evidence of early regional heritage is found at the Saint John Nepomuc Cemetery and the German Cemetery, which anchor the map's historical geography alongside long-established family routes like Murley Road and Baumgartner Road. The terrain is characterized by named lowland stretches such as Pleasant Valley, Coon Valley, and Gunderson Valley, illustrating how the township's development followed the natural contours of the Driftless Area's unglaciated topography.
