Contour Ring Clusters
This Classification is Under Development.
Where there are several Contour Rings in one area, Dartefacts instead of listing them separately merges them into 'Contour Ring Clusters'. It is important to note that Contour Ring Clusters listed will all contain Contour Rings of the same height, so if there is a mix of 210 m and 220 m high Contour Rings then there will be two separate listings.
Do not assume that a Contour Ring Cluster listed is legally accessible.
