The ever-changing Ohio River flows through time as well as space, connecting us with the past as it links Pittsburgh with Cincinnati, Cairo, and New Orleans. Always a River views the Ohio through the perspective of history, geography, political science, economics, and literature. Essays by Scott Russell Sanders, John A. Jakle, Hubert G. H. Wilhelm, Michael Allen, Darrel E. Bigham, Leland R. Johnson, and Boyd Keenan tell about the settlement period of the river, its economic importance, the different phases of engineering over a long period of time, and the river as an eco-political system. This revised edition includes a new introduction with a historical overview, as well as an up-to-date map and index.
