In 1955 researchers from the Science Museum of Minnesota conducted a surface survey. They collected 17 potsherds and seven stone tools (four knives or scrapers, two hammerstones, and a celt). This prompted the museum to return in 1958 for what remains the site's most extensive excavation. They determined that the majority of the site's artifacts dated from the Middle Woodland Period, with rare finds indicating earlier and later occupation as well. This helped establish the probable cultural sequence of the site.
