The 45×90 points on a world map
The original marker for the 45×90 point in North America; the sign was later amended to explain that the real location is actually approximately 324 m (1,063 ft) behind and to the left of the marker on the ground.

The 45×90 points are the four points on Earth 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 45°0′0″N 90°0′0″W / 45.00000°N 90.00000°W / 45.00000; -90.00000 which is located on land at 410 m (1,345 ft) 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.[1] It re-opened September 12, 2017.[2]

The point has become something of a pop culture phenomenon thanks to Gesicki's Tavern in the tiny cluster of establishments in Poniatowski.[3] They once sold 45×90 T-shirts and registered visitors as members of the "45x90 Club".[3] 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.[4] 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 45°0′0″N 90°0′0″E / 45.00000°N 90.00000°E / 45.00000; 90.00000, which is at an elevation of 1,009 m (3,311 ft) above sea level. This point is located in a desolate region of the Xinjiang Uyghur Autonomous Region of China, near the Mongolian border, approximately 240 km (150 mi) 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.[5] Their visit found no monument or any physical recognition of the status.

45°S, 90°E

The search for Malaysia Airlines Flight 370 was near the coordinate 45°S, 90°E. The coordinate is closest to the red dot labeled as Gaofen 1 at the bottom, halfway between the center and left side of the image.

Located in the southern Indian Ocean, 45°0′0″S 90°0′0″E / 45.00000°S 90.00000°E / -45.00000; 90.00000 has an ocean floor depth of 3,197 m (10,489 ft) below sea level and is 1,244 km (773 mi) southeast of the nearest uninhabited island of Île Saint-Paul, 1,480 km (920 mi) northeast of Elephant Spit on Heard Island, 1,569 km (975 mi) east north east of Port aux Français in the Kerguelen Islands, 2,425 km (1,507 mi) north of Antarctica, 2,448 km (1,521 mi) southwest of the closest inhabited land of Augusta, Western Australia, 4,080 km (2,535 mi) southeast of Réunion Island, and 5,550 km (3,450 mi) southeast of Benguerra Island, Mozambique, and 5,800 km (3,600 mi) southeast of Mossel Bay, South Africa.

In March 2014, the location in the southern Indian Ocean was the subject of an aerial search for the missing Malaysia Airlines Flight 370, after potential debris were spotted by satellite centered on the 45°S, 90°E location.[6][7]

45°S, 90°W

Located in the southern Pacific Ocean, 1,297 km (806 mi) west south west of Guaitecas in Chile, and 3,070 km (1,910 mi) north of Antarctica, 45°0′0″S 90°0′0″W / 45.00000°S 90.00000°W / -45.00000; -90.00000 has an ocean floor depth of 4,180 m (13,730 ft) below sea level.


Each 45x90 point is the antipode - the point on the opposite side of the each - of another 45x90 point.

The southern Indian Ocean location and the point in Wisconsin are antipodes of each other.

The southern Pacific Ocean location and the point in China are antipodes of each other.
