Read all about it

The Basin Oil Field Tipi Rings (48CA1667) were recorded by personnel from the Office of the Wyoming State Archaeologist in 1982. This was done as part of a cultural resource inventory of a proposed Energy Transportation Systems, Inc. coal slurry pipeline route. The site is located on the top of a ridge overlooking the confluence of the floodplains of Caballo Creek, the Belle Fourche River and several smaller drainages. It is composed of a dispersed lithic scatter, a concentration of ceramic fragments, and eleven stone features including seven stone circles, one stone cairn, a fire hearth, and two amorphous scatters of cobbles which may be disturbed stone circles. The site represents a Middle Missouri tradition occupation during the Late Prehistoric or Protohistoric Periods. A possible Late Archaic component was also noted. The site contains significant data relevant to two current research issues: 1) the movement into the Powder River Basin of pottery bearing groups of the Middle Missouri tradition, which may have included groups closely related to the Mandan, Hidatsa or Crow; and 2) the functions and cultural associations of stone circles.
