White Mountains. Inyo National Forest. Northeast of Bishop (Mono County, California, US)notes Goethite Pseudomorph after Pyrite. These crystals, originally composed of Pyrite (iron sulfide), have been altered chemically by hydrothermal activity. Goethite, a hydrated iron oxide, has replaced the Pyrite. However, the Goethite pseudomorphs retain the shape and form of the original Pyrite crystals. These specimens were weathering out of a mineralized vein in the Early Cambrian Reed Dolomite in the White Mountains.keywords: Geology, earth science, mineral, mineralogy, crystal, isometric
