Marengo Ridge - McHenry County Conservation DistrictCategory:OUTDOORS & PLAY
The major glacial feature at Marengo Ridge Conservation area is the Marengo Ridge, from which the site derives its name. Left by the retreating Wisconsin glacier, the Marengo Ridge moraine is 40 miles long and 3 miles wide, creating one of the steepest vertical moraines in Illinois, at 1,050 feet above sea level. This rugged, fire-protected topography supported wooded communities dominated by oak species. Site features hiking trails, campground, picnic shelters, scenic views, x-country skiing, and fishing.
