Pink Pipestone, or red catlinite, is a type of clay (argillite, or metamorphosed mudstone) from quarries located and preserved in Pipestone National Monument outside of Pipestone, Minnesota. Because it is fine-grained and easily-worked, it is prized by Native Americans for use in making sacred pipes such as calumets and chanunpas. In watercolor, this clay makes permanent, soft pink that has low tinting strength and lightly staining.
