2016 Map of Castle Rock

About this map

The Driftless Area of Grant County is defined by its deep coulees and ridges, where the Blue River and the Fennimore Fork carve through the landscape near the landmark Castle Rock. This survey documents a rural network of valleys and hollows that historically dictated settlement patterns and road placement in southwest Wisconsin. Significant family and community landmarks are scattered across the terrain, including Saint Johns Cem near the eastern border and the German Cem to the south. Small, localized communities like Pleasant Valley, Coon Valley, and Gunderson Valley are connected by narrow roads such as Blue School Rd and Level Valley Rd. The map illustrates the persistent agrarian character of the region, where topographical features like Cedar Cliff and Cass Hollow remain central to the local geography.
