Oak Ridges Moraine
Exploring the Oak Ridges Moraine
Unique Landscape
Rolling over the southern Ontario landscape, the Oak Ridges Moraine stretches from Lake Ontario to the Niagara Escarpment in the west and the Trent River in the east. This geographical phenomenon was formed by glaciers during the last ice age (70,000-10,000 BC), as channels in the ice created piles of sediment that were to become the Moraine.
Water, Water Everywhere
Composed mainly of gravel, sand and some silt, the Moraine acts as a giant sieve, purifying and filtering rainwater into an aquifer that in turn supplies local and regional ground water flows. The Moraine is essentially a rain barrel, supplying around 250,000 people with drinking water. It acts as the watershed divide between Lake Simcoe and Lake Ontario and releases water into over 65 watercourses that flow north and south into Georgian Bay, and the Lakes Simcoe, Scugog, Rice and Ontario. The Oak Ridges Moraine is also the headwater for a number of rivers, including the Humber, the Don and the Rouge Rivers.
Diverse Flora and Fauna
Boasting an impressive array of flora and fauna as well as a variety of landforms ranging from woodlands to wetlands, the Oak Ridges Moraine supports a distinctive and fragile ecosystem. Many regionally and provincially rare species live here, such as the Hooded Warbler and the Jefferson Salamander, two of the multitude of plants and animals that call the Moraine their home. Many of these creatures are considered threatened or endangered, accentuating the importance of this special area of the Greenbelt.
Explore the Moraine
Incredible hiking trails wind across the Moraine, allowing for a closer look at the irreplaceable natural environment and varied wildlife. With 250km of trails currently completed and future plans to extend the paths along the entire length of the Moraine, both those who enjoy a leisurely stroll in the countryside as well as more serious hikers can enjoy the beauty of the Moraine.
