Book excerpt: The Ice Age National Scenic Trail meanders across the state of Wisconsin through scenic glacial terrain dotted with lakes, steep hills, and long, narrow ridges. David M. Mickelson, Louis J. Maher Jr., and Susan L. Simpson bring this landscape to life and help readers understand what Ice Age Wisconsin was like. An overview of Wisconsin’s geology and key geological concepts helps readers understand geological processes, materials, and landforms. The authors detail geological features along each segment of the Ice Age Trail and at each of the nine National Ice Age Scientific Reserve sites. Readers can experience the Ice Age Trail through more than one hundred full-color photographs, scores of beautiful maps, and helpful diagrams. Science briefs explain glacial features such as eskers, drumlins, and moraines. Geology of the Ice Age National Scenic Trail also includes detailed trail descriptions that are cross referenced with the science briefs to make it easy to find the geological terms used in the trail descriptions. Whatever your level of experience with hiking or knowledge of glaciers, this book will provide lively, informative, and revealing descriptions for a new understanding of the shape of the land beneath our feet.
