7U7 Ranch (7-U-7 Ranch), Bagdad Mine area, Hillside, Eureka District, Yavapai Co., Arizona, USA

StandardDetailedBy ChemistryMineral Photos (6)Search GoogleMineral Report for Region

Granite pegmatite. Conversations with Cornelius Hurlbut over the terrain of this currently "lost" locality was that it was out in the open on a very flat knoll barely rising above the dirt access road level. No road actually went to the prospect which was about 35-70 meters from the road. There were no real landmarks.
