Silver Dollar Mine, Adams Mine group (Adams claims), Kofa Game Range, Castle Dome District, Castle Dome Mts, Yuma Co., Arizona, USA
Small Cabinet, 8.7 x 4.8 x 4.4 cm
An interesting locality specimen of brown vanadinite, that is probably leaning towards endlichite in chemistry if the color is any guide. I have not seen this material before, myself. Harold purchased this from the caretaker of the at-the-time defunct Red Cloud Mine, in 1990. Ex. Harold Urish Collection.
