NORTH AMERICAN CONTINENTAL POLE OF INACCESSIBILITY

A pole of inaccessibility can be defined as the center of the largest circle that can be drawn within an area of interest without encountering a coast.


In North America, the continental pole of inaccessibility is on the Pine Ridge Reservation in southwest South Dakota about 11 km (7 mi) north of the town of Allen, 1,650 km (1,030 mi) from the nearest coastline at 43.36°N 101.97°W. The pole was marked in 2021 with a marker that represents the 7 Lakota Values and the four colors of the Lakota Medicine Wheel.
