A kettle hole is a depression or basin formed by the melting of a block of ice left behind by a glacier. As the glacier retreats, the ice melts and creates a hollow in the ground, which can fill with water, forming a pond or lake. These features are commonly found in glacial landscapes. Kettle holes are important for local ecosystems, providing habitats for various plants and animals. They can also contribute to groundwater recharge and serve as natural water storage areas. Kettle holes are often associated with other glacial features, such as moraine and drumlin formations.
