The Ohio River corridor defines the industrial and residential character of this mid-century survey, with the dense riverside development of Midland standing in sharp contrast to the wooded ridges of the Pennsylvania Game Commission lands. Heavily influenced by the river economy, the landscape features significant infrastructure including Lock and Dam No 7 and the Montgomery Dam, which regulate the vital waterway near Georgetown Island.
