Natives and tourists had long known about Makauwahi Cave, but it was Burney who, in August 1992, first grasped its significance for understanding Hawaii’s long and varied history, when he, Lida, and researchers Storrs Olson and Helen James from the Smithsonian Institution stumbled on the site while on vacation.
He typically locates them at the periphery of the sinkhole, against the cave’s walls, where the stratigraphy is clearer.
