Thousands of orange crocoite crystals cover most of the surface and cavities of this specimen. The crocoite is generally translucent, although some crystals are opaque and some nearly transparent. They vary greatly in size, too, ranging from 0.1mm to over 10mm in length. Many of the crystals are long, thin, and prismatic, while others are stubby. The luster varies, too, from dull to vitreous, although some of the nearly black crocoite crystals have a nearly metallic luster. The host rock is mostly limonite and goethite, plus there is quite a bit of some dull, light brown mineral as a crust, plus some interesting opaque white crystals that I have not identified.
