The locality at Bergen Hill dates back to the 19th Century, and some of the most classic of all New Jersey Trap Rock specimens were found around this area. This specimen is more than likely from the Erie Railroad cut as I have seen similar pieces in various collections from the same locale. It is comprised of translucent, light golden color Calcite scalenohedra which are associated with white blocky Apophyllite crystals and small acicular "sprays" of Natrolite on matrix. Ex. Kosnar Collection.
