Near State College, Pennsylvania, the Tudek Site was a prehistoric stone quarry where Native Americans obtained Bald Eagle Jasper for stone tools during the Early and Middle Archaic periods, roughly 8000 to 3500 BC. Discovered in 1978 and excavated as highway construction was planned, it produced an unusually dense concentration of artifacts and several jasper varieties. Its importance lies especially in its connection to the nearby Houserville Site: archaeologists concluded that jasper was mined and heat-treated at Tudek, then taken to Houserville for shaping and broader tool production. This division of labor has helped illuminate Archaic lifeways, regional exchange, and changing stone-working technology in central Pennsylvania.
