The easternmost extent of the western Great Plains begins in Indiana with the central tallgrass prairie. The "Grand Prairie Peninsula" occupies northwest Indiana roughly between Lake Michigan and the Wabash River. Although most of the Indiana prairie has gone the way of the bison and prairie chicken, there are places where the prairie survives and thrives. Nature Walks on the Indiana Prairie highlights 29 outings that focus on the Indiana prairie, savanna and wetlands that are found in the Grand Prairie natural region. This guide book briefly describes the natural and social history of each nature walk. Accurate maps and detailed highway directions and trail descriptions help in planning your trips. Numerous color images of this unique region enhance the pages. The author has personally experienced each nature walk and has provided up-to-date information in this handbook, making it the most comprehensive walking guide written on the Indiana prairie.
