the 45th Parallel

Oconto, Wisconsin

Old Mission Light

Between Oconto and Marinette there is a small rest area on the west side of Highway 41 with this marker. Another monument placed by Frank Noyes, this plaque marks the point where the 45th Parallel intersects the highway. The point halfway to the pole is marked by two different monuments north of Beaver and Menomineee, MI (see Halfway to the Pole for an explanation).
