Pohaku Kani, Kahakuloa, Maui

This is the famous "Bellstone" of Kahakuloa. If tapped properly with a rock, the Bellstone will make a reverating sound. But that's not the half of it... The residents of Kahakuloa Valley have a long tradition of embedding the piko or umbilical cords of newborns in this rock, and if you look carefully at the picture, you'll see the bore holes.
