Overview

  • Seasonal low tides in July fully uncovered two 115-foot panels at Pililaau Army Recreation Center and Pōkaʻi Bay, revealing 26 stick-figure and abstract carvings etched into lithified sandstone
  • The panels feature 18 anthropomorphic figures—ranging from 15 centimeters to over two meters tall—and symbols interpreted as pre-contact ceremonial records and ancestral warnings about rising seas
  • Following exposures on July 12 and around July 23–24, Army archaeologists completed field documentation and set up regular monitoring protocols within days
  • Cultural Resources Management teams facilitate more than 50 annual visits by Native Hawaiian practitioners for site rituals, interpretive sessions and community stewardship
  • Environmental monitoring units track seasonal tide shifts and storm impacts to guide sand redistribution efforts and protect the fragile carvings from erosion
