Ancient Hawaiian petroglyphs, some dating back at least 500 years, have emerged on Oahu's coastline, offering a rare glimpse of more than two dozen human-like stick figures. Seasonal ocean swells have, for the first time in years, cleared away the sand that typically conceals these historic carvings.
Easily discernible at low tide, the intricate carvings are revealed as gentle waves wash over the neon-green algae clinging to the sandstone. This marks the first occasion the entire panel has been fully visible since its initial discovery nine years ago by two visitors at a US Army recreation centre in Waianae, an hour's drive from Honolulu.
