The Calhan Paint Mines District, 5EP3258, Colorado, presents exposures of an exceptional clay source. When the area also produced prehistoric Ceramic stage sites, it provided the opportunity for both pottery and potential clay source analysis by optical petrography, X‐ray diffraction, and neutron activation. Although the main purpose of this study is the characterization of the ceramics and outcrop clays, results from a limited number of samples suggest that the colorful clays, the figurative “paints,” of the Calhan Paint Mines were purposely used in prehistoric times as clay source materials for ceramic production. The Calhan Paint Mines are quite possibly the only prehistoric Plains Ceramic stage clay source currently confirmed within the state of Colorado. © 2002 Wiley Periodicals, Inc.
