Kittatinny Valley

Kittatinny valley is the name given to that part of the Great Appalachian valley which traverses northern New Jersey. Its width varies from 10 to 13 miles, and it stretches from the Delaware river to the New York state line. On the northwest it is bounded by the Kittatinny mountain, the crest of which is composed of hard Oneida conglomerate and sandstone. On the southeast lie the pre-Cambrian crystallines of the highlands, while the rocks of the valley are chiefly limestones and shales of Cambrian and Ordovician age. In addition to this wide trough-like depression there are several long, narrow valleys within the highlands themselves, the rocks of which are of the same age as those of the Kittatinny valley. Small detached areas of the same formations occur along the eastern border of the highlands, and evidently underlie in part, at least, the Newark formation.
