42 Papers and 20 abstracts by Jane L. Forsyth, glacial geologist; geology maps and botany maps, photographs bibliography.

In Ohio Rocks , skilled writer and geologist Albert Dickas takes you to some of the state's most interesting geologic chapters. At Blackhand Gorge the sandy deposits of an ancient sea were cut and sculpted by glacial meltwater. In Scioto County you can trace the margins of a ghost river that flowed before the ice ages. And you can visit the historic Buckeye Furnace, which produced enough pig iron to make Ohio an industrial giant in the nineteenth century.

Atlases accompany v. 1, pt. 1; v. 2; and v. 5-7.

There is much more for children to discover about Ohio than first meets the eye. Under Ohio: The Story of Ohio's Rocks and Fossils, by geologist Charles Ferguson Barker, takes young readers underground to reveal the fascinating story of Ohio's geology. Barker presents this story through colorful illustrations, sending his readers down the "Ohio Timepike" and back a billion years to when the earth under Ohio split, creating faults that cause the earthquakes felt today. He tells of colliding continents that pushed up mountains taller than the Rockies and of the tremendous impact of the Ice Age, which profoundly altered the landscape. He shows fossil coral and shells, evidence of the tropical seas that once covered the state. Under Ohio offers a rich, interactive source of information for kids, parents, teachers, or anyone who would like to uncover facts about the state's geological features. Armed with a list of Ohio's best sites for rock and fossil hunting, junior geologists will want to set out on an adventure that can begin in their own backyards.

The 25 road guides of Roadside Geology of Ohio, complete with 59 maps and figures and 172 photographs, lead you from one corner of the state to the other�from the flat till plains of the west to the hilly eastern Allegheny Plateau, and from the Ohio River valley to the Lake Erie shoreline.

A “superbly written, richly illustrated” guide to the animals who lived 450 million years ago—in the fossil-rich area where Cincinnati, Ohio now stands (Rocks & Minerals). The region around Cincinnati, Ohio, is known throughout the world for the abundant and beautiful fossils found in limestones and shales that were deposited as sediments on the sea floor during the Ordovician Period, about 450 million years ago—some 250 million years before the dinosaurs lived. In Ordovician time, the shallow sea that covered much of what is now the North American continent teemed with marine life. The Cincinnati area has yielded some of the world’s most abundant and best-preserved fossils of invertebrate animals such as trilobites, bryozoans, brachiopods, molluscs, echinoderms, and graptolites. So famous are the Ordovician fossils and rocks of the Cincinnati region that geologists use the term “Cincinnatian” for strata of the same age all over North America. This book synthesizes more than 150 years of research on this fossil treasure-trove, describing and illustrating the fossils, the life habits of the animals represented, their communities, and living relatives, as well as the nature of the rock strata in which they are found and the environmental conditions of the ancient sea. “A fascinating glimpse of a long-extinct ecosystem.” —Choice
