Guide to Rocks and Minerals of Illinois, Guide for Beginning Fossil Hunters, and Guide to Illinois Caverns

Special 3 book package price $12.00

The Guide to Rocks and Minerals appeals to rock hounds from amateur to science teachers. It is a comprehensive reference on the state’s rocks and minerals, with more than 40 color plates that display excellent examples of rock types ranging from fluorite (the state mineral) to the world-renowned geodes of western Illinois. The photographs are accompanied by detailed descriptions of both common and very unusual rocks and minerals in Illinois. Useful identification flow charts and keys help the reader identify their specimens. In addition, the guide summarizes the basic geology of Illinois and discusses the physical properties of rocks and minerals, ways to collect and identify samples, and the importance of rocks and minerals to society. The Beginning Fossils Guide includes full color photographs of fossils and rocks and additional fossil drawings and plates. The Guide to Illinois Caverns is as close to an actual tour as one can get due to Illinois Caverns being closed to the public due to the white-nose-syndrome (WNS) that is devastating the bat population across the country.  Through this guide you will be able to imagine the cave feature by feature, and, along the way, you'll learn about the area's unique karst terrain, the plants and animals of the area, and the processes that formed and continue to change the caverns and surrounding area.

Michael J. Chrzastowski.
2005. Full color map poster. 24 x 30 inches.

$7.00 sale price $5.00

The thriving metropolitan area extending inland along 70 miles of Lake Michigan shoreline—known as Chicagoland—was made possible by glacial and coastal processes. This map poster provides a visual perspective of the area not available from the ground. The accompanying text explains how geologic processes laid the foundation for the development and continued prosperity of the state's largest city. Today evidence of these processes is revealed by four distinct landscapes: (1) the rolling hills and ridges of Wheaton Morainal Country; (2) the Y-shaped Chicago Outlet Valley that made possible the historic Illinois and Michigan Canal, the Chicago Sanitary and Ship Canal, and the Calumet-Sag Channel; (3) the Chicago Lake Plain, a low-sloped expanse of land that holds most of the City of Chicago; and (4) the Zion Beach-Ridge Plain, a migratory coastal sand plain.
