The mountain covers portions of Harmony, Lopatcong, Franklin and Washington Townships; the main summit rises to 1,086 feet (331 m), and is located in Harmony.

[3] An 1834 description read, Scott’s Mountain, lying in Greenwich, Oxford and Mansfield t-ships, Warren co., forms part of the chain of the South mountain, of which this portion covers much of the area of the three t-ships above named.

The height of the mountain here may be 700 to 800 feet above the tide, and it is composed of granitic rock, based on, or breaking through, limestone.

It abounds with iron of several varieties, which, for nearly a century, has been extensively worked, near Oxford furnace; where Messrs. Henry and Jordan are, now, extensively engaged in the iron manufacture.

The Mountain is generally well wooded, and the valleys fruitful.
