Darwin District, Inyo Co., California, USA
A mining area located principally in secs. 11-14, 23-25, T19S, R40E, MDM, around Darwin.
The locality is particularly famous for scheelite crystals. The old report that stolzite occurs from this locality was substantiated by Moore (2006). The opaque gray specimens of "scheelite" may be mostly pseudomorphs of stolzitre after scheelite, while the transparent to translucent crystals which fluoresce blue white in short wave ultraviolet are probably perfectly good scheelite.
