A pair of vacationers from Texas discovered previously-unknown petroglyphs thought to be at least 400 years old on a Hawaiian island beach.
Lonnie Watson and Mark Louviere made the archeological find on Oahu. They located 10 unusually large (5-foot) images carved in sandstone across 60 feet of beach.
"For some reason there was a beam of light—just a beam," Watson says, per the state Department of Land and Natural Resources. "It landed right on one of them and for some reason I just turned my head." Researchers have now found another 17 images.
