Exact Center of the Northern Half of the Western Hemisphere

A total renovation of the site was completed in September 2017. There is now a large slab with a bronze marker on the exact spot, which is about 1,100 feet from the roadside. A wide, nicely manicured path leads from the parking area to the marker, with flowers and park benches along the path and at the marker itself. New signage as well.

Can you find the mistake on the sign? 45 x 90 is NOT a geological marker - it's a geoGRAPHical marker! If it were a special outcrop of rock, it would be geoLOGical. Whoever puts up these signs needs a science lesson!

Exact Center of the Northern Half of the Western Hemisphere

The marker Mr. Barrington alludes to is near the town of Poniatowski, WI. It's not in town -- nothing much is. Poniatowski is one of those rare Polish names with a superabundance of vowels. I have it on good authority that you don't need them all. Instead, you say the name Pon-uh-TUSK-y.

It would be discourteous to suggest that Poniatowski is in the middle of nowhere. Rather, let us say that it is in the middle of everywhere. Here is the text of the marker:

"This spot in Section 14, in the Town of Rietbrock, Marathon County is the exact center of the northern half of the Western Hemisphere. It is here that the 90th meridian of longtitude (sic) bisects the 45th parallel of latitude, meaning it is exactly halfway between the North Pole and the Equator, and is a quarter of the way around the earth from Greenwich, England. Marathon County Park Commission"

Exact Center of the Northern Half of the Western Hemisphere

You mentioned for Wisconsin there are a lot of "halfway to the north pole" sites. This may be the best. Near Poniatowski, just north of Wis. 29, is the Exact Center of the Northern Half of the Western Hemisphere (45 north latitude, 90 west longitude). When last visited, it boasted a sign in a fenced-in area, and a small marker you could place your foot on (it's about a foot off the ground, so no standing.).
