| Late Paleoindian and Early Archaic dart points from Choke Canyon. No buried Paleoindian sites were found, probably because they were either washed away or deeply buried by Archaic-period floods. Collectors have found Early Paleoindian artifacts such as Clovis and Folsom points in the surrounding uplands and there is little doubt that these peoples would have also frequented the ancient Frio River. |
