Excavations
In the summer of 1986, an archaeological survey was conducted at the site to determine if the site were eligible to be listed on the National Register of Historic Places. This was done by the Glenn Black Laboratory of Archaeology at Indiana University with financing from the Indiana Department of Natural Resources.
Professional surveys in the 1980s revealed a long line of archaeological deposits that was strung out along the riverbank for at least 500 metres (1,600 ft). Types of artifacts found at the site include Kirk cluster projectile points from the Early Archaic period, various types of scrapers, hammerstones, large celts, bifaces, and many other kinds of stone tools. Most of these tools were composed of Wyandotte chert, a high-quality stone that is more plentiful in Harrison County and surrounding regions than anywhere else in the world. Charcoal was present at the site in abundance, along with multiple hearths; the lack of damage to the stones at the site has been taken as an indication that the inhabitants were capable of constructing wood fires with good aeration. Their fires were not composed exclusively of wood: evidence exists that they employed coal, oil shale, and perhaps manganese dioxide as fuel. Artifacts recovered through test excavations were subjected to radiocarbon dating, which produced a wide range of dates: because some artifacts were dated as much as eight thousand years before others, and because many dates were either too ancient or too recent for the Archaic period that produced the characteristic projectile points found at the site, it is plain that the results were flawed in some way.
