  • 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 millios of years ago. Fluctuating seas full of marine life, widespread floodplains and rivers choked 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.
