The Ellerbusch Site (12-W-56) is a small but significant archaeological site in the southwestern part of the U.S. state of Indiana. Unlike many sites created by people of the same culture, it occupies an upland site near a major river floodplain. Its existence appears to have been the result of the coincidence of periods of peace and growth in the related Angel Site, which led some townspeople to leave their homes for new villages that were more convenient for resource gathering.
