Research was conducted to determine the origin of the sandstone used to make palettes found at the Moundville site in west-central Alabama. Sandstone samples were taken from two localities: one near Tuscaloosa, Alabama, which contains an abundance of Upper Pottsville Formation sandstone; and one near Guin, Alabama, which contains an abundance of Lower Pottsville Formation sandstone. The sandstone samples were ccompared petrographically to artifact samples from Moundville. In terms of mineralology, texture, and color, the Moundville palettes more closely resemble the Upper Pottsville Formation sandstone from Tuscaloosa than the Lower Pottsville Formation sandstone from Guin. This finding supports the conclusion that sandstone palettes were produced locally in the Moundville region.
