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.
