This granite reef and pinnacle has been known to exist for many years, as there is a break over it in a large swell, but no details were reported until an exploratory party visited it on 3rd October 2010, to investigate what had shown up on a side-scan sonar image from a reef survey by the Council for Geoscience as a massive mound of rock. What they found is a huge granite corestone tor with a variety of interesting topographical features, on a low profile rocky bottom with sand patches.
