Welcome to Marengo Ridge
Marengo Ridge Conservation Area is one of McHenry County’s most popular and treasured areas. It contains over 818 acres of oak and hickory woodlands interspersed with spruce, aspen, ash and sumac groves.
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.
Cache Your Way Question
Snakes are either oviparous (egg laying) or viviparous (live bearing). Snakes that are viviparous nourish their young through a placenta and yolk sac. On average in the world, only 30% of snake species reproduce in this manner.
How many snake species in McHenry County are viviparous?
