This map image is composited from two United States Geological Survey publications, "Bedrock geologic map of northern New Jersey" (Miscellaneous investigations series no. I-2540-A) and "Bedrock geologic map of central and southern New Jersey" (Miscellaneous investigations series no. I-2540-B), held in the Lewis Library Map Collection at Princeton University. The three map sheets from these publications are combined into a single image; sheets containing geological cross sections are presented individually.
