Illinois River Country Nature Trail, Connecting great lakes to great rivers

Princeton Loop (map)


Description: About ten miles southeast of Princeton, the Illinois River dives
southward, slipping into the wide north-south valley originally carved by an ancient Pleistocene version of the Mississippi River. The associated natural habitats are mostly open grassland types, dotted with closed-canopy woodlands such as those at Warnecke Woods, Hennepin Canal Parkway State Park, Miller-Anderson Woods Nature Preserve, and Condit's Ranch Campgrounds.

Prairies dominate the remainder of this loop. The McCune Sand Prairie sits on super-porous glacial moraine soils, resulting in a unique assemblage of dry-country grasses, wildfl owers and small trees, including a number of species more common to regions much further west. Visit the Hennepin & Hopper Lakes Restoration Project to view how the Illinois River floodplain is being reclaimed and restored.
