The Big 7

The Big 7

The Big Seven Poles of Inaccessibility refer to the five largest land masses on Planet Earth (continental poles), plus the two real poles, Northern and Southern:

I’m calling them the Big 7 purely in reference to the enormity of the land masses and the fact that these have traditionally been thought of as “all” of the Poles of Inaccessibility

The coordinates of five of these poles were calculated by Garcia-Castellanos and Lombardo – see table here.

The Antarctic Pole remains as a “generally accepted” location, commonly accepted in the Exploration world.  I’ve been unable to track down who first made the calculation but it was probably somebody on the 2nd Soviet Antarctic Expedition in 1958, led by Aleksei Treshnikov, who were first to achieve that location.

The arctic pole has actually changed position!  Prior to a review of satellite mapping in 2013, the pole was thought to be 133 miles away from where it is now calculated to be – now known as the False Northern Pole of Inaccessibility.

On this page you will find a discussion on the use of the term “pole” which is commonly used to reference these seven points – another reason for distinguishing these as the “Big 7”.  For smaller land masses, on this site, we use the term Point of Inaccessibility.
