Summary:

Pg. 296-309. Glassboro gravel. Called "Fossiliferous gravel" in earlier papers, because many of its pebbles are fossiliferous. Occurs at lower elevations than Bryn Mawr gravel. Abundant in New Jersey and southeast Pennsylvania. It is the yellow gravel which caps the watershed between the Atlantic and the Delaware at a height of nearly 200 feet. Is older than Philadelphia red gravel.
Probably named from occurrence at Glassboro, Gloucester Co., NJ.
