Researchers have found a red ochre (hematite) quarry in the Rocky Mountains, Wyoming. The mining is dated tt 12,480-12,505 years ago at the Powars II site. This mine is now the oldest hematite mine found in the Americas. Clovis points have been found there with other projects, tools and shell beads, animal bones and antlers. The site was mined for 1000 years. Some of the projected points came from as far away as Texas. The mined hematite found its way across North America. Further excavations are planned.
The research was published in the Proceedings of the National Academy of Sciences.
