FINCH MINE, HAYDEN, GILA CO., AZ

 

 

 

After leaving the Ray Mine on May 29, 2002, Don, Patrick and I proceeded south on Highway 177 to Hayden Junction. We turned left onto Haines Road, an unmarked dirt road that goes up the southeast side of Keystone Canyon. This is strictly for four-wheel drive and high clearance. We followed the directions and map in Minerals of Arizona, by Neil R. Bearce. This, incidentally, is an excellent book for anyone who wants to collect in Arizona. The directions took us right to the mine.

The Finch mine consists of a single U-shaped tunnel that goes in about 200 feet, turns to follow a contact zone for about 75 feet, then turns again to come out. The two portals are seen in the pictures above. We didnít go in all the way, because the timbering looked shaky, and the tunnel isnít very high. Even Patrick had to stoop over!

The most interesting specimens here are Vanadinite and Wulfenite crystals covered with a layer of Hemimorphite , Quartz or Descloizite. We even got some with Descloizite over Quartz over Wulfenite!
