Shifting Sands Reveal 400-Year-Old Petroglyphs in Hawaii

Shifting sands on a Hawaiian beach have revealed — and then concealed again — carvings that Hawaii's indigenous people made on the shoreline at least 400 years ago. Two tourists from Texas stumbled across the petroglyphs last month on Oahu's Waianae Coast on the western side of the island. "It was just a stroke of luck," Lonnie Watson, one of the visitors, said in a statement issued by the Hawaii Department of Land and Natural Resources.
