The majority of the 18 known sites within the Osage USGS Quadrangle and the Blacksville USGS Quadrangle on the environs of the Pennsylvania and West Virginia border are of the Monongahela Culture. The Worley village Complex (46Mg23) dates to about AD 900. It is located within the Blacksville USGS Quadrangle, as is the recently found Wana village site, which was revealed by infrared photography. A field test at the Wana site confirmed pottery, shell, and flint present. It has not yet been studied.
