About this property

21SL55 is a precontact Native American archaeological site in the Boundary Waters of northern Minnesota, United States. It was occupied by the Blackduck culture of the late Woodland period sometime between 700 and 1500 C.E. Located on a small island in what is now Voyageurs National Park, the site is known only by its Smithsonian trinomial. It contains well-preserved faunal remains, a possible ricing jig, and other subsurface features. The site was listed on the National Register of Historic Places in 1988 under the name Archeological Site 21SL55 for its local significance in the theme of prehistoric archaeology. As an island site occupied exclusively during one cultural period in what is now a protected area, 21SL55 was nominated for its potential to illuminate regional subsistence patterns of the late Woodland period.
