Clay shed from the rising mountains, associated with the Taconic orogeny formed the shale units. The warm sea water created perfect conditions for abundant biological activity and the Cincinnatian Series is highly fossil-bearing, outcropping across much of southwest Ohio in river beds, hillsides and road cuts. Ohio's State Invertebrate Fossil ...
The Ohio River at Cairo is 281,500 cu ft/s (7,960 m 3 /s); [1] and the Mississippi River at Thebes, Illinois, which is upstream of the confluence, is 208,200 cu ft/s (5,897 m 3 /s). [66] The Ohio River flow is greater than that of the Mississippi River, so hydrologically the Ohio River is the main stream of the river system.
The Falls, circa 1929. The area is located at the Falls of the Ohio, which was the only navigational barrier on the river in earlier times. The falls were a series of rapids formed by the relatively recent erosion of the Ohio River operating on 386-million-year-old Devonian hard limestone rock shelves.
Model of tropical storms effects on Cincinnati Arch region in the Ordovician. The Cincinnati Arch formed from ocean sediments deposited between 488 and 444 million years ago on the North American Continent. The geology is characterized by layers of shale interspersed with layers of fossiliferous limestone. [4]
Stone fortification and mounds at the Devil's Backbone rock formation. Devil's Backbone is a rock formation and peninsula formed by the flow of Fourteen Mile Creek into the Ohio River, and is currently situated in Charlestown State Park near Charlestown, Indiana, and across the Ohio River from Louisville, Kentucky.
Ohio Stadium was built on grass, but through the years the field has alternated between the real stuff and synthetic. A look at its playing surfaces.
The Mill Creek is a stream in southwest Ohio. It flows 28.4 miles (45.7 km) [1] southwest and south from its headwaters in Liberty Township of Butler County through central Hamilton County and the heart of Cincinnati into the Ohio River just west of downtown. The section of Interstate 75 through Cincinnati is known as the Mill Creek Expressway.
U.S. Route 52 (US 52) runs east–west across the southern part of the state of Ohio along the Ohio River, passing through or very near the cities and towns of Cincinnati, Portsmouth, and Ironton. For its first 19 miles (31 km) or so, the highway runs concurrently with Interstate 74 (I-74) and I-75 before it winds through downtown Cincinnati ...
