Trip Report - Aug 25, 1993 - Jack Parsell
From Interstate 29 in SD, use exit 246 and go E and then N on route 127 to White Rock Road, which is 1 mile S of the ND - SD line. Lakeview Cemetery is at the NE corner of this intersection. Go E for 2 miles on the White Rock Road, then 1 mile N to the ND state line. Turn E and go a little over 1/2 mile on a farm lane to the ND - SD stone marker #1. There is a drainage ditch along the right (S) side of this road. The tri-point should be between the ND - SD marker and the river but no monument or marker could be found in that area. The Boise de Sioux River is a little over 0.1 mile E of the ND - SD marker.
If approaching from the N, take route 127 S from Wahpeton, ND to the White Rock Road corner described above. Note that the hamlet of White Rock, although it shows on most maps, is a ghost town with a population of 2 in 1993.

Date Visited: August 25, 1993; Revised July 2007
Access Route: The original survey of the ND-SD boundary line was on the 7th standard parallel north, and was surveyed in 1891 -92. The first marker (Initial Monument, inscribed IN. MT.) was placed 9 chains (594') W of the Boise de Sioux River riverbed. The U.S. Corps of Engineers changed the channel of the river leaving MN land on the W side of the river at the ND-SD line, so the tri-point is not in the middle of the river.
From I-29 in SD take exit 246 and go E 11-1/2 miles then N 4 miles en Route 127 to 101 ST which is 1 mile S of the ND-SD line. Lakeview Cemetery is at the NE comer of this intersection. Go E on 101 ST for 2 miles then left (N) on an unmarked gravel road for 1 mile to the ND-SD state line at the intersection of 183RD AVE SE and 102ND ST SE. Turn right (E) and go about 1/2 mile to the end of a farm lane to the ND-SD Initial Monument.
The Initial Point as inscribed on the monument is 9 chains east (IN. PT. 9 C.E.). There is a drainage ditch along the right (S) side of this lane. The tri-point should be between the ND-SD Initial Monument and the river but no monument or marker could be found in the area. The Boise de Sioux fiver is a little over 0.1 mile E of the Initial Monument.

In Jack Parsell's description of this tripoint, he states to take exit 246 and go east on route 127. That road is locally marked as 105th street. 127/105th street curves north then you turn east onto 101st St (Jack calls it White Rock Road) at the Lakeview Cemetery. Turn north onto an unmarked gravel road (my GPS called in 480th Street) and travel one mile to the ND-SD state line. Jack then states to travel east on a farm lane to the marker. That farm lane is locally marked as 102nd Street but "farm lane" is a better description as it is unpaved and has tall weeds growing in the lane. The red tripoint marker is clearly visible at the end of the lane.

This tri-corner is the second closest to the convention site. It is approximately 225 miles northwest of Worthington and is more in keeping with the "middle of nowhere category." Take your GPS. As of 2011 there was no marker. We drove along the farm lane as far as we dared then walked up to the Boise de Sioux River (not much of a river). However, in October this was not a "white shoe" friendly place - kind of a mud slog.
Directions (adapted from Parsell's book): From Worthington go west on I-90 to I-29 in SD. Go N on I-29 to exit 246, about 160 miles. Go east about 12 miles and then N on route 127 to White Rock Rd. Go E 2 miles on White Rock Rd, then 1 mile N to the ND state line. (If you cross the RR tracks on White Rock Rd. you went too far.) At the state line turn E, go a little over 1/2 mile on a farm lane to the ND-SD stone marker. There is a drainage ditch along the right side of this road. Park where the lane stops and walk along the left side of the drainage ditch toward the river. Unmarked, the tri-point is somewhere between the ND-SD marker and the Boise de Sioux River.
