The last twenty miles of the Lehigh River is considered a subsequent stream because it is directed by the geologic structure it encounters. The Lehigh Mountains prohibit the rivers southern flow. Bordering the northern side of the river is Rittersville Hill.

The crystalline rocks of Lehigh Mountains are broken east of Bethlehem by the Saucon Gap. At the eastern side of the gap, the river makes a sharp turn and flows north for one mile to get around the hard nose of Freemansburg Mountain. Once the river has passed Freemansburg Mountain, it turns east again and continues to the Delaware River in Easton.

The Lehigh flows through Cambrian aged limestone between Allentown and Easton. This is the same limestone that has been quarried and used as building stone and road slag.
