Stretching nearly 1,200 miles and meandering across the state of Wisconsin is the Ice Age Trail, which roughly follows the terminal moraine and marks the southern most point of glaciation from the last Ice Age. Along the route, glacial features such as kettles, potholes, eskers and glacial erratics can be found. When the ice retreated around 10,000 years ago, the landscape became littered with thousands of lakes and various types of wetlands. Small ponds or kettles, like this one, may have at one time been a large chunk of ice that sank into the soft ground sediment leaving a depression for water to pool.
