The southern ridge traverses the boroughs of Prospect Park, Haledon, North Haledon, Hawthorne and the township of Wyckoff, running generally north to south. Starting at the Great Falls of the Passaic River, the southern ridge rises gently to the north, culminating at an elevation of 602 ft just inside of Hawthorne, near the border with North Haledon and Wyckoff. The summit marks the highest peak of Goffle Hill, though comparable peaks exist in the northern part of the ridge. The southern ridge is distinguished from the northern part of Goffle Hill by the presence of trap rock glades and vertical basalt cliffs which rise abruptly on portions of its eastern flank.
