Canyon Creek Arizona identified as major source of pre-Columbrian turquoise
Canyon Creek, located on the White Mountain Apache Indian Reservation in eastern Arizona, was one of the known turquoise sources exploited by preColumbrian indigenous groups, but before today, it wasn’t considered a significant site. A new study of the area has now shown that the mines were actually a major supplier of the bluish-green mineral during the 13th - 14th centuries, when it was exported to sites as far as 80 miles away. Lead isotope analysis of samples indicates that Canyon Creek turquoise is unique, making it distinguishable from other sources in the southwest.
