STS062-081-007 Ohio River Valley, Kentucky, U.S.A. March 1994 Apparent are the incised floodplain of the Ohio River, the dark landscape of eroded stream valleys, and the lighter terrain of cultivated hilltops and ridgelines. Barely discernible are the faint outlines of Covington, Kentucky, and western Cincinnati, Ohio (bottom center), west of which is the confluence of the Great Miami River and the Ohio River and still farther west, the convergence of Kentucky, Indiana, and Ohio. Bright, highly reflective Cincinnati-Northern Kentucky International Airport west of Covington is visible (bottom center).
