PIPESTONE, Minn. (AP) – The Pipestone National Monument in southwestern Minnesota says it will stop selling pipes following decades of tribal complaints that the sales desecrate sacred grounds. Minnesota Public Radio News reports that Faith Spotted Eagle of the Yankton Sioux Tribe calls the pipestone from which the pipes are carved “the blood of our people.” Native Americans will continue to demonstrate pipestone carving for visitors and the monument’s store will open a location downtown where pipes can be sold.
