The Lehigh River snakes through the center of this Lehigh Valley survey, serving as a primary corridor for both the Central Railroad of New Jersey and the Lehigh Valley Railroad. This era is defined by the heavy industrial extraction of the region, evidenced by the numerous Quarries and the Dewey Heights Quarry near Cementon. The landscape transitions from the river's industrial banks to the educational grounds of the Mary Immaculate Missionary College and onto the suburbanizing townships of North Whitehall and South Whitehall.
