Evidence that the Avebury stone circle and its associated monuments show knowledge of past Polar positions

Relationship of Avebury site to previous polar positions

Unavoidably this now has to get down to some number crunching. Distances and bearings have been worked out with the ‘How far is it?’ program available on the Internet. It works out the distance between and the bearing to and from two points on the Earth surface as given by their co-ordinates.

Previous Pole positions (Table 1)

This means that 80,000 years ago Avebury was tropical at about 30 degrees North. Between 50 and 80,000 years ago Avebury was within the Arctic Circle at 67 degrees North. Between 12 & 50,000 years ago Avebury was temperate at 48 degrees North. Finally between 12,000 years ago and the present Avebury was also temperate having not moved much at 51.5 degrees North.

Extent of previous polar displacements (Table 2)

Each Polar displacement seems to be roughly the same order of magnitude at about 10% of the earths circumference. Depending on the direction this can have dramatic effects on certain locations and hardly any effect at all on others. Avebury for example was moved from the latitude of the tropics to the arctic circle during the YKP to GSP displacement but hardly any latitude at all during the HBP – CNP displacement.
