Roadside Geology of Ohio
Ohio's bedrock reveals a rich story of the ancient landscapes and animals--foot-long clams, massive meat-eating reptiles, lumbering mammoths--that existed thousands to hundreds of millions of years ago. Fluctuating seas full of marine life, widespread floodplains and rivers chocked with sediment, and mile-thick ice sheets from the north all shaped Ohio's present landscape. But Ohio's geologic tale has a human side too. Native Americans fashioned razor-sharp flint spear points; oil, gas, and coal fueled several economic booms; sandstone and limestone built communities and thriving economies. 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. Mark Camp's clear writing explains how caverns and disappearing streams form in karst; why mud cracks, ripple marks, and cross-bedding layers are entombed in sedimentary rock; and how grooves up to 10 feet deep were gouged into the limestone of Kelleys Island. From deserted boomtowns to Ohio's big cities, Roadside Geology of Ohio thoroughly reveals the Buckeye State's fascinating and dynamic geology.

This is an excellent guide. The author brings alive the rich geological history of Ohio (which being fair can be a bit drab compared to other parts of the country). I found this book very useful on a recent outing to the Huron river near Norwalk Ohio. The river cuts along two very steep and tall cliffs that seem very odd. Turns out these cliffs are beach cliffs of ancient Lake Maumee. I am looking forward to purchasing the Roadside geology of Indiana by the same author.
