Trip Report - Aug 25, 1993 - Jack Parsell
The inscription on the plaque reads, "TRI-STATE MARKER 1859 SET AT THE JUNCTION OF THE STATES OF MINNESOTA, IOWA AND DAKOTA TERRITORY BY FEDERAL LAND OFFICE SURVEY OF MINNESOTA'S WESTERN BOUNDARY". The plaque goes on to report that after being damaged by vandalism in the early 1900's, it was restored in 1938. Then, after damage by vehicular traffic in 1979, it was restored at its present site in 1981.

This is now a 4-way intersection. See "Apex to Zenith" Issue #73 Second Quarter 2006, p23 for latest info on this corner.

The "tee intersection" is now a 4 way intersection with 10th Avenue going N-S and llth Street going E-W. My GPS reading for the marker was N 43/30.024 and W 96/27.198. My GPS also noted that it was 1.06 miles to the tripoint from where K16 reaches the MN line. Slightly to the west of where K16 reaches the MN line, 20th Avenue goes north to a junction with I 90. Depending on where one is coming from and/or going to, this may be a good route to take. 20th Avenue as it proceeds north is also called Rock County # 12 or # 17 (couldn't decipher my handwriting).

Coordinates: N43d 30.025m, W96d 27.197m, elev. 1411 ft
Date Visited: July 10, 1991; Revised July 2007
Access Route: From I-90 exit 1 Jasper-Pipestone in MN go right (S) on Rock County 17 (20th AV) for 7.5 miles to a T intersection at llth ST (in MN, 100th ST in IA). Tun right (W) and go 1 mile to gravel 10th AV and the tri-point.
There is a monument on the NW comer of the T intersection in SD but the actual tri-point is a 1/2" diameter pin in the middle of the paved road. Note that the street signs on each comer are different depending on which state you are in. The inscription on the plaque on the monument reads, TRI-STATE MARKER 1859 SET AT THE JUNCTION OF THE STATES 0F MINNESOTA, IOWA AND DAKOTA TERRITORY BY FEDERAL LAND OFFICE SURVEY OF MINNESOTA'S WESTERN BOUNDARY. The plaque goes on to report that after being damaged by vandalism in the early l900's, it was restored in 1938, damaged by vehicular traffic in 1979, and restored to its present site in 1981.

Are you convention bound? Why not bag a tri-point? Iowa shares a tri-corner with South Dakota and Minnesota. This one is people and rental car friendly. No hill to climb, fence to negotiate, river to ford, nor dirt road to voilate the rental car contract. It is about 60 miles west of Worthington, MN.
The following directions have been adapted from Jack Parsell's "Tri-State Corners in the United States". From Worthington MN go W on I-90 about 30 miles to exit 12 (Highway 75). Go S on Hwy. 75 about 15 miles to state route 9. Go W on route 9 about 12 miles to Hwy. 182. Turn N and go to Larchwood on 9/182. From Larchwood, leave route 9, go straight N on route K16 for about 3 miles to the MN state line. Turn left (W) on a boundary line road and go about 3/4 mile to the Tri Point marker and monument.
Jack describes a marker in the middle of the road. When Keith and I visited this tri-corner in July 2007 we found the marker had been moved to the side of the road - see photo.
Reminder: road conditions and landmarks change over time. Getting lost or temporarily misplaced is always an option.
