These seven obsidian flakes were excavated in 1966 at the Lewis site in Pawnee County by Kansas Historical Society archeologists. In 2005, they were analyzed using x-ray florescence (XRF) testing, an elemental analysis that matches the composition of the artifact to the composition of known sources. The obsidian at the Lewis site was determined to be from Valles Rhyolite from the Cerro del Medio member and the Cerro Toledo Rhyolite from the Obsidian Ridge member, both places found in the Jemez Mountains in New Mexico. Thus XRF studies help archeologists to learn about ancient trade patterns. The Lewis site has Pratt Complex (Middle Ceramic period), Smoky Hill aspect (Middle Ceramic period), and Great Bend aspect (Late Ceramic period) occupations.

Date: 1000-1700 CE
