A pole of inaccessibility marks a location that is the most challenging to reach owing to its remoteness from geographical features which could provide access. The term describes a geographic construct, not an actual physical phenomenon, and is of interest mostly to explorers.
In North America, the continental pole of inaccessibility is in southwest South Dakota (43°26′N 102°23′W / 43.433, -102.383 (Continental Pole of Inaccessibility in North America))[citation needed], located 1650 km (1024 mi) from the nearest coastline. An alternative documented[12] location is 43°22′N 101°58′W / 43.36, -101.97 (Pole of Inaccessibility North America).
