The Crenshaw site (3MI6) is a multiple-mound Caddo ceremonial center located in the Great Bend Region of the Red River in Miller County, Arkansas. It is known for the presence of both "pre-Caddo" or Fourche Maline materials and later Caddo materials. It also has some characteristics that separate it from many other sites including a causeway between two of the mounds, a deposit of deer of over 2,000 deer antlers, and deposits of stacked human skulls and detached mandibles representing over 300 individuals.[2][3]
