The Hawai’ian name for Black Rock is Pu’u Keka’a, and ancient Hawaiians believed that this was the place where their spirits went to jump off to join ancestors forever. Unlucky souls who could not be shown the way by their family ‘aumakua (guardian animal spirit), would wander and attach themselves to rocks in the area. This is likely where the “it is bad luck to take a Hawai’ian lava rock” superstition comes from.
