Analysis of the human remains from Smith Mounds Three and Four in nort
hern Minnesota suggests the mounds were built around 95 BC by people o
f the Laurel Culture. Each episode of burial seemed to have contained
the dead from a one-year interval of time. Women and subadults under t
he age of three were underrepresented in the mound and were presumably
interred elsewhere at times. Evidence of mortuary practices includes
skulls with occipitals removed, punctured long bones, cut marks, and r
ed ocher. Pathological changes in the bones suggest infection produced
significant morbidity. Other pathology resulted from trauma, degenera
tive joint disease, and congenital abnormalities.
