From Russell: "from NW 1/4, NW 1/4 sec. 33, T127N, R64W, spillway of Elm Lake 10 miles W of Fredrick, Brown county, South Dakota" (note: these township and range coordinates do not match the given description and appear to be one range to the east)\r\nFrom Martin: "the spillway of Elm Lake 10 miles west of Fredrick, South Dakota, Brown County in NE 1/4 of NE 1/4 of sec. 6; T. 127 N; R. 64 W." (note: though these given coordinates differ from those reported in Russell, they also plot out to be one range too far to the east, not agreeing with the written description or the location of the lake.)
