Exceptional crystals for this locality, of this rare zeolite species. Seldom found at any US locality in good size, let alone from the historic copper mines of Northern Michigan. In fact, this is a highly unusual environment and association for them to form in, but there they are. The crystal in center is 3 cm, not counting the sidecar to its left. Seldom do you see a crystal of this magnitude, though. From the late Ernie Schlichter's noted Copper Country sub-collection. Joe Budd Photos.
