Oak Ridges Moraine, Glacial landform in south-central Ontario, Canada.
Oak Ridges Moraine is a glacial ridge extending about 160 kilometers across south-central Ontario with rolling hills and varied terrain. The landform contains forests, lakes, wetlands, and grasslands arranged in a naturally diverse landscape.
The ridge formed roughly 13,000 years ago at the end of the last ice age when retreating glaciers left behind thick deposits of rock and soil. This created the most substantial glacial accumulation found across the province.
The ridge shapes the local landscape with forested hills and open spaces that attract hikers and nature observers. People value it as a place to connect with the natural environment and experience seasonal changes throughout the year.
The ridge can be explored through various trails and paths suitable for different abilities and interests. Wear sturdy footwear and check weather conditions, especially in wetter areas near lakes and wetlands.
The ridge contains kettle lakes formed when buried ice blocks melted, creating depressions that filled with water. These lakes and surrounding wetlands serve as critical habitats for threatened species like Jefferson Salamanders and Monarch Butterflies.
