USGS Topo · Published 1985About this map
The Richard J Dorer Memorial Hardwood State Forest dominates the eastern portion of this regional survey, where the rugged topography of the Root River Valley contrasts with the surrounding agricultural plains. The landscape is defined by its drainage networks, including the North Branch Root River and South Fork Root River, which carve through the limestone terrain of the Driftless Area. Significant geological features such as the Niagara Cave and numerous quarries indicate the subterranean karst activity characteristic of this border region.
