On 03/18/2016 Harvey Smith, Jim Herring and myself decided to visit the area of the Rainbow Quarry and Aztec Tank after exploring the Contact and Pauline mine sites. This meta-quartzite mine area covers 920 acres and is located about seven miles northwest behind the town of Goodsprings Nevada. This unusual uplifted mound of Aztec sandstone is a very hard, uniquely multi-colored meta-quartzite that can be drilled, cut, and then polished, honed and utilized for a multitude of applications.
