FOV 3.2 x 2.2 mm. Found Oct 1995. MOB coll. This is from an (EDS) analyzed find. So despite the highly iridescent pyrite like tarnish, this is arsenopyrite. The shape is right and broken xls show fresh silvery interiors. Aresonpyrite is rare at MSH, These xls are good for the locality. Stereo child photo.

FOV 2.8 x 2.2 mm. This is the original parent - now a child photo. The difference is fiber optic halogen (old) vs ordinary tungsten (new).
