HONOLULU, HAWAII—A series of at least 17 petroglyphs estimated to be 400 years old was revealed by shifting sands on the Waianae coast of Oahu. Hawaii’s Department of Land and Natural Resources (DLNR) and the U.S. Army have been working to record and protect the images, which are etched into the sandstone. “We can now come up with a plan to further protect and preserve this site,” Army archaeologist Alton Exzabe told the Honolulu Star Advertiser. He explained that one of the glyphs—a human figure—measures between four and five feet from head to toe and has distinct hands and fingers. He explained that many petroglyphs in Hawaii are about one foot tall. “They are an important part of Hawaii’s culture and while sands have covered them again, in time they will reappear and we want to make sure people know that they are fragile and culturally sensitive and should only be viewed; not touched,” added Alan Downer, administrator for the DLNR State Historic Preservation Division.
