Deposit FLUORITE CRYSTAL UP TO 1 IN. IN FISSURES AND VUGS, DESCRIPTION OF LARGEST VEIN. FLUORITE OCCURS IN A FAULT ZONE. THE E SIDE OF THE HILL IS THE HANGING WALL AND DOWN-THROWN SIDE OF THE FAULT ZONE THAT DROPS METAMORPHOSED CRET STRATA DOWN AGAINST PALEOZOIC LIMESTONE ON THE FOOTWALL. CUBIC FLUORITE CRYSTALS IN PLACES ALMOST PERFECTLY CLEAR AND RANGING IN SIZE UP TO 1 IN. ACROSS OCCUR IN FISSURES OR NUGS.
