Trenton clays here described as commonly red or red-spotted grading into blue at bottom of pits. In some places upper layer is white clay, and locally a black lignitic clay occurs beneath the blue clay; elsewhere a sand bed underlies the clay. Belong in Raritan formation [Broad use of Raritan, which included Magothy formation.] Two mi east of Trenton the clays are dug in a number of pits along Pond Run. They are locally known as Dogtown clays, from occurrence at Dogtown, near Trenton. Age is Late Cretaceous.
