The Marengo Moraine was created about 24,000 years ago by the Wisconsin glacier. The ridge is made up of rocks, gravel, sand and finer sediments that were carried within or pushed ahead of the ice sheet as it advanced and left behind as it melted. Where the ice melted and advanced at an equal rate, the debris piled up at the glacier’s leading edge. The result is a deposit that is up to 280 feet deep, several miles wide and 40 miles long. At its highest point, the ridge stands 1,050 above sea level. In Marengo Ridge Conservation Area, the area around Shelter #2 offers excellent vantage points for surveying the geological history of the area.
Marengo Ridge is a nature lovers paradise! Home to a number of ecosystems and dozens of wildlife species, this site can be enjoyed for a short walk, an entire day walking the trails, or even a weekend camping trip.
