The sludge - gray Onandaga River divided the city as it met Lake Erie beneath a steel bridge: the
valley carved by the river was a treeless expanse of railroad tracks, boxcars, refineries, cranes, chemical plants, and,
looming over all of this, the smokestacks of the steel mills — squat, black, and enormous — on which Steelton's existence had once depended.
Still in the Harz Mountains, at Quedlingburg, a gorgeous town with a delightful Romanesque church and well - preserved red - roofed houses, where the 10th century stronghold of Burgberg
looms imposingly
over the town, is another narrow - gauge railway - the Selketal Railway - that runs through the Selke
Valley.
