48PA3135 has a variety of features, hearths, stone circles, metal working areas, and artifact clusters. In addition to the metal objects that are described here, there is also an assemblages of glass beads.
Three features have what seems to be debris from metal working (Features 2, 9, and 13). Feature 2 appears to be just a metal workshop activity area, while both 9 and 13 have the metal debris inside a stone circle and are also associated with beads.
This site provides an excellent opportunity to study what may be some temporal variation in occupation (based on differences in glass bead assemblages from features 9 and 13) as it relates to metal working.
