Quick Summary

Indonesia's worst wildfires since 2015 are endangering the world’s oldest cave paintings in Sulawesi, with some dating back over 67,000 years. Fires and extreme heat from these blazes threaten to accelerate corrosion and obscure the prehistoric artwork, including hand stencils and figures interacting with animals, located within Maros-Pangkep Cave and nearby areas. As of October 23, more than 270 hectares of the national park surrounding the caves have burned, with firefighters battling fires as close as 800 meters to the cave sites.

Story summary

Indonesian wildfires, driven by a severe El Niño event, are threatening world’s oldest cave paintings in Sulawesi, which date back more than 67,000 years. While Sumatra and Borneo are hit hardest, fires have spread to Sulawesi, including South Sulawesi where limestone caves house these ancient artworks. Researchers from Australia's Griffith University found that a reddish-colored hand stencil in a cave on Muna island off Sulawesi is at least 67,800 years old. The heat and smoke from the fires risk accelerating the deterioration of these invaluable historical artifacts despite no direct fire damage yet.
