45×90 points


The 45×90 points are the four points on Earths which are halfway between the geographical poles, the equator, the Prime Meridian, and the 180th meridian.

45°N, 90°W

The best-known and most frequently visited such point is which is located on land at above sea level in the town of Rietbrock, Wisconsin near the unincorporated community of Poniatowski. An incorrect geographic marker was placed there by the Marathon County Park Commission, but in 2017, it was removed and relocated to the actual location. It re-opened September 12, 2017.
The point has become something of a pop culture phenomenon thanks to Gesicki's Tavern in the tiny cluster of establishments in Poniatowski. They once sold 45×90 T-shirts and registered visitors as members of the "45x90 Club". Since 2006, the Wausau/Central Wisconsin Convention & Visitors Bureau has been the holder of the official "45x90 Club" registration book. The book is on loan from the Gesicki family. Upon becoming a member of the "45x90 Club", the Wausau/Central Wisconsin Convention & Visitors Bureau will give new members a commemorative coin.

45°N, 90°E

The only other 45×90 point located on land is, which is at an elevation of above sea level. This point is located in a desolate region of the Xinjiang Uyghur Autonomous Region of China, near the Mongolian border, approximately northeast of Ürümqi. Administratively, it is on the border of Qitai and Qinggil Counties. Greg Michaels, an American, and Ru Rong Zhao, a taxi driver from the closest town of Qitai, itself 110 km to the south-southwest, visited this point on April 13, 2004 and documented the visit on the Degree Confluence Project. Their visit found no monument or any physical recognition of the status.
