MACROFLORAL ANALYSIS, CHARCOAL IDENTIFICATION, BONE COLLAGEN EXTRACTION, AND AMS RADIOCARBON AGE DETERMINATION OF SAMPLES FROM THE FORT LOOKOUT II SITE (39LM0057), LYMAN COUNTY, SOUTH DAKOTA

The Fort Lookout II site (39LM57) is a multicomponent site located on an MT-1 terrace along the eroding west bank of the Missouri River (Lake Francis Case) at the southern end of the Fort Hale bottoms, Lyman County, South Dakota. Archaeological investigations at the site include excavations in 1950, 1951, 1986, 1999, and 2001. The site demonstrates village occupation during the Initial Middle Missouri as well as subsequent historic components (Katherine Lamie, personal communication March 2, 2015). Five charcoal fragments, the light fraction from one macrofloral sample, and a bison long bone shaft fragment collected from two features and one additional excavation unit were submitted for identification, bone collagen extraction, and AMS radiocarbon age determination. The samples are expected to date to approximately 1080 RCYBP, which is the age returned on human bone from the village (Katherine Lamie, personal communication March 2, 2015).
