More than 12,000 years ago, an immense flow of glacial ice sculpted a landscape of remarkable beauty across Wisconsin. As the glacier retreated, it left behind a variety of unique landscape features. These glacial remnants are now considered among the world’s finest examples of how continental glaciation sculpts our planet. The Ice Age National Scenic Trail is a thousand-mile footpath that highlights these landscape features as it travels through some of the state’s most beautiful natural areas. The Trail is entirely within Wisconsin and is one of only eleven National Scenic Trails. The trail passes right through the Groll’s backyard! Link to the visitor center here:
