The Late Archaic deposits at Cold Oak produced an abundance of wild and domesticated plant remains, animal remains, and stone and wooden tools. Wild plant remains consisted primarily of hickory, walnut, acorns (red and white oak), and chestnut. Domesticated plants found in storage pits included charred and uncharred seeds of sunflower, goosefoot, knotweed, marshelder, squash, and possibly maygrass.
Among the other preserved plant remains were bits of cordage and a wooden tool that may have been used for weaving. The recovery of the latter suggested that textile production took place at the site. Large quantities of wood chips and a celt fragment indicated that woodworking also may have taken place at Cold Oak.
Animal resources recovered from the shelter included white-tailed deer, turkey, squirrel, black bear, box turtle, and fish bones, crayfish fragments, and freshwater mussel shells.
