The Kettle Moraine State Forest is a state forest in southeastern Wisconsin. The chief feature of the reserve is the Kettle Moraine, a highly glaciated area. The area contains very hilly terrain and glacial landforms, such as kettles, kames and eskers. The 56,000-acre (23,000 ha) forest is divided into two large and three small units, which are spread across a hundred miles. All units include a portion of the Ice Age National Scenic Trail and most units have horse/snowmobile trails. Several areas of trail loops for hiking, biking and skiing can be found in the northern and southern units.
