This bench mark, known as "DW 3457", is an easy find once you know where to look. The location is along the north side of a paved road between Highways 16 and 79 approximately four miles south of Rapid City near a golf course.

Looking north from the paved road.
The bench mark is located on one of the most prominent rocks across the ROW fence.
