Summary:
Bridgeton formation of Columbia group, here named, is predominantly gravel, but contains both sand and loam and occasionally clay. Differs somewhat from overlying Pensauken fm [restricted] and from underlying Beacon Hill formation, though difference is not always great. Is unlike Beacon Hill in that it contains bits of ironstone. Like Beacon Hill, contains much decayed chert.
