Red Pipstone is 'sacred' for a number of Native American tribes. The major American source for this stone, also known as Catlinite, is Pipestone, Minnisota. The quarries in Pipestone are under the control and management of Native Americans. The stone is carved into a Calumet, which is when assembled with a pipestem (cedar wood, or somesuch) The entire assembly then becomes what is called a chanunpa, which is then used to produce the smoke that carries prayers to the Creator Spirit. In 1986, I received a pipe, from Lakota Dr. Chuck Ross. It was carved by his father.
