Tribal elder Gordon Yellowman opens a bag of Sweet Grass, which is one of several herbs that he uses in the Sundance priest rituals that he performs for the Arapaho-Cheyenne tribe, in El Reno, Oklahoma June 12, 2014. As Yellowman watched a tornado near Oklahoma City on the television news last year, he and other tribal priests did what the Native American people in Oklahoma have done for centuries - held a sacred ceremony to steer the tornado away from their land in one of the most tornado-prone parts of the country.

Sweet grass basket makers Celestine Ravenel (L) and her cousin Adeline Mazyck display their wares in their open air shop in Mount Pleasant, South Carolina December 18, 2013. The Gullah tradition of basket making has been handed down for generations in the Charleston area. Unionized machinists in Washington state last month rejected a labor contract that would have guaranteed Boeing's new jet program, known as the 777X, be built there.
