The New International Encyclopædia/Lehigh
LEHIGH, lē'hī. A river of eastern Pennsylvania. It rises a few miles east of Wilkesbarre and flows southeast, breaking in picturesque gorges through the Blue Mountain range, till it reaches Allentown, Lehigh County, where it turns northeast, and enters the Delaware at Easton, after a course of about 120 miles (Map: Pennsylvania, F 2). It is followed for the greater part of its course by the Lehigh Valley Railroad, and passes through a region rich in anthracite coal and iron, for which it is an important outlet. By means of locks and dams it has been opened for slack-water navigation as far as Whitehaven, 84 miles from its mouth.
