Do you think winter in northern Wisconsin is long? Imagine a glacial winter that lasts thousands of years. Snow falls on top of snow. The polar ice cap expands and creeps into North America, covering this area.The Ice Age National Scientific Reserve preserves evidence of the glaciers. The Reserve consists of nine sites administered jointly by the Wisconsin Department of Natural Resources and the National Park Service.The Ice Age National Scenic Trail provides the opportunity to hike along the glacier's edge and view glacial features. Scan this code for a link to more trail information.The last great episode of the Ice Age, called the "Wisconsin Glaciation," ended about 10,000 years ago. Creeping ice radically altered the terrain. Debris deposited when the glaciers melted formed an amazing variety of glacial landscape features across the state.Glacial meltwater transformed landscapes in other ways-especially here. Torrential meltwater sculpted a basalt gorge and potholes that are highlights on the Pothole Trail.

The Pothole Trail Begins HereThis trail overlooks the edge of the famous gorge known as the Dalles of the St. Croix River. Along the mostly flat 4/10-mile trail, that includes some oneven ground, you will find potholes of many sizes and shapes. The trail is also the western terminus for the 1200-mile Ice Age National Scenic Trail. Head east, and this could be the beginning of a very long walk.
