Bench Mark "DW 6443" was established in the Black Hills by the U. S. Geological Survey sometime around the year 1898. It was referenced to the Deadwood Datum which depended upon a bench mark at Deadwood, South Dakota. The location is along the north side of Road 292 near the SE Corner of Section 33, T2S, R3E of the Black Hills Meridian. It is approximately 8 miles west and 4 miles north of the town of Custer, South Dakota. Recovered by Kurt Luebke, Jenny Stukel and Jerry Penry.
