Pipestone is a type of sedimentary rock primarily composed of clay and quartz. It is known for its soft texture, making it easy to carve. This stone is often used to create ceremonial pipes, which hold cultural significance for many Native American tribes. The color of pipestone can range from red to pink, and it is valued for its beauty and symbolism. The most famous source of pipestone is the Pipestone National Monument in Minnesota, where the stone has been quarried for centuries. The site is considered sacred by many Indigenous peoples, who continue to use pipestone in traditional practices and art.
