Tissington Spires is an example of Reef Knoll.
The limestone that forms the White Peak was laid down about 325 million years ago when the area was situated a few degrees south of the Equator and a tropical lagoon. Reefs were mostly formed from corals and became pure white limestone; they were mostly found at the fringe of the lagoon and tend to be more resistant to erosion.
