What to know about South Dakota

  • Eastern South Dakota is surveyed from the Fifth Principal Meridian; the Black Hills in the west use the Black Hills Meridian, and the Sixth Principal Meridian touches the southern edge.
  • Because more than one meridian applies, the state name alone may not settle it — preserve any principal-meridian notation from the source record.
