Roadside Geology of Indiana

More about the book

Hundreds of millions of years ago, warm, coral-rich seas deposited mud on the ocean floor, and in time it became limestone--the cornerstone of Indiana geology. From the fossil-studded rocks and twisting caverns of the southern hills to the coal seams of the Wabash Valley and the shifting sands of the glacial plains, Roadside Geology of Indiana provides a window to a vibrant and dynamic past. With this book as your guide, tour Indiana's timeworn topography and discover fossilized reefs, mastodon skeletons, geodes, buried bedrock valleys, and the site of a meteorite impact.
