Destruction of many of Arizona’s fossil logs in the 1890’s by persons seeking Quartz minerals was responsible for having the area declared a national monument in 1906. Explorers would use dynamite and blast whole logs apart to get to the Amethyst/Quartz. From the collection of Joan Shaw and her daughter Cindy Garoutte.
