What is the Oak Ridges Moraine?

Detailed answer

The Oak Ridges Moraine is a significant geological feature in southern Ontario, Canada, stretching approximately 160 kilometers in length and 15 kilometers in width. Formed around 12,000 years ago during the last ice age, it is a result of glacial deposits, including sand, gravel, and clay, left behind by the melting of glaciers. The moraine plays a crucial role in the region's ecosystem, supporting a diverse range of flora and fauna, and serving as a vital source of groundwater recharge. In 2001, the Ontario government passed the Oak Ridges Moraine Conservation Act to protect this unique landform and its ecological integrity. The moraine is also home to numerous kettle lakes, such as those found in the Oak Ridges Moraine Trail, which spans over 280 kilometers. The conservation efforts have been successful in preserving the moraine's natural beauty and ecological significance, with over 3,900 hectares of land protected within the moraine's boundaries.
