There are several dozen Vanadinite crystals on this specimen. They are members of the arsenous variety called Endlichite. They occur as hexagonal crystals like regular vanadinite, but tend to form prisms, rather than occur in a tabular form. They have a dull, brownish-yellow color, a bright sub-metallic luster, and are dimly translucent. They are small, not exceeding 0.3"(8 mm) in length, and their form is rather poor, as none of the larger crystals seem to be complete; this is due to natural causes, though, because there is little damage. These crystals rest on a dark goethite/limonite host rock.
