Calver Island is a historic archaeological site located on the Susquehanna River in Swatara Township, Dauphin County, Pennsylvania. It is known as Pennsylvania Site 36DA89. Geographically, Calver Island is a "midchannel" island formed from the coalescence of two longitudinal shoals that merged as one landform. It was only then upon the unification of the land, estimated at 5200 years before present, where it would've been inhabitable by Native Americans. Read more on Wikipedia
