Mark J. Camp

Dr. Mark J. Camp, an Associate Professor of Geology in the Department of Environmental Sciences at the University of Toledo, initially studied Pleistocene nonmarine Mollusca of lacustrine deposits of Ohio, Michigan, and Indiana. After receiving his doctorate from The Ohio State University, he taught geology at Earlham College in Richmond, Indiana for two years before returning to Toledo. Since 1998, Dr. Camp has also been Director of Northwest Ohio District 2 Science Day, creating research opportunities for students in eight northwestern Ohio counties.

Dr. Camp's ten books represent significant service to his discipline and the general public, especially Roadside Geology of Indiana and Roadside Geology of Ohio. Dr. Camp is the author of six books on railroad depots and also serves as a National Director of the Railroad Station Historical Society and manages its website.

Railroad Depots of East Central Ohio

RAILROAD DEPOTS OF EAST CENTRAL OHIO (2018): The hilly Alleghany Plateau of eastern Ohio was crossed by a number of primarily east-west rail lines heading toward Chicago, St. Louis, and ports on the Mississippi River during the latter part of the nineteenth century. These lines, eventually part of the Baltimore and Ohio, Erie, New York Central, Nickel Plate, and Pennsylvania systems, were joined by  shorter lines extending from Lake Erie to the Ohio River, most notable the Wheeling & Lake Erie, designed to tap the coal and clay riches of the region.

In order to serve the populace, railroad depots were needed. Smaller communities like Dalton and Dundee received typical combination depots designed to provide passenger, baggage, and freight accommodations. Separate passenger and freight depots were erected at larger communities including Ashland and Canton. The arrival of the automobile brought a decline to local passenger service and a closing of depots. Some depots continued to serve the railroads in other ways, others were sold and moved from trackside, but many were demolished. Few remain today.


Roadside Geology of Ohio

ROADSIDE GEOLOGY OF OHIO (2006): Ohio’s bedrock reveals a rich story of the ancient landscapes and animals—massive meat-eating reptiles, foot–long clams, lumbering mammoths—that existed thousands to hundreds of millions 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; and 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.
