Roadside Geology of Indiana

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. As you travel across Indiana`s time-worn topography, discover fossilized reefs, mastodon skeletons, geodes, ancient bedrock valleys, and the site of a mysterious meteorite impact. Authors Mark J. Camp and Graham T. Richardson divide Indiana into four geographically distinct regions: the fossil-rich limestone of the southeastern hills, the karst topography of the south, the coal-bearing rocks of the Wabash lowlands, and the glacially buried north. Numerous maps and cross sections reveal Indiana`s geology for easy exploration. Copyright (C) Muze Inc. 2005. For personal use only. All rights reserved.
