Trip Report - July 21, 1991 - Jack Parsell
Off the E side of the road, in line with the tripoint, is an old witness post with markings indicating that the corner is in the center of the road. William Harris set a wood stake at the tripoint in 1817 when he surveyed the west and north boundaries of Ohio. A brown stone replaced the stake in 1869. During a joint OH-MI resurvey of the line in 1915, the brown stone was replaced by a block of granite set in a bed of concrete buried 2.5 feet deep in the center of the road. Finally, on August 28, 1999, 30 surveyors from the three state societies dedicated a new plaque which was mounted on top of the 1915 stone. This plate is in a crypt about a foot below the road surface at the center of the road. A steel cover plate at the road surface protects the monument and allows access.

The road to the tri-point is COPE Road. I had it as a line road.

On the way to the late July '07, 20th Highpointers Konvention near Wausau, WI, we bagged this easy tri-point which called for a short detour north from the Ohio Turnpike, I-80/90. Pictured, looking north, the marker is in the lower right corner (road-center), MI in the top right, OH in the lower right, and IN to the left of road-center. All aspects of this tri-corner are as described in Jack Parsell's guide with the exception of the witness marker to the east - the top of this cement post was broken off sometime after Jack's visit in '91. We accessed the site via Rt120 (Territorial Rd.) in MI and traveled south on Cope Rd. .8mi where there's an obvious road surface break from gravel to blacktop at the MI/OH state line. Another big clue is the red granite marker on the left shoulder, 130ft (so inscribed) north of the state's tri-junction. The heavy metal plate in the road's center can be removed to expose the 6in deep crypt and the nifty engraved plaque within (pictured).
