Pipestone is a type of soft, reddish stone primarily found in the Pipestone National Monument in Minnesota. This stone, also known as catlinite, has been used by Native American tribes for centuries to create ceremonial pipes, which are significant in their spiritual practices. The stone's softness allows for easy carving, making it ideal for artisans. The quarrying of pipestone is a sacred tradition for many Indigenous peoples, who believe it connects them to their ancestors. The process of extracting and shaping the stone is often accompanied by rituals and prayers, emphasizing its cultural importance beyond just a material resource.
