K'gari's Lakes Dried Up 7,500 Years Ago Despite Heavy Rainfall, Ancient Sediment Reveals

Ancient sediment analysis from K'gari (formerly Fraser Island), the world's largest sand island off Australia's Queensland coast, shows that some of its deepest lakes disappeared around 7,500 years ago despite an era of unusually heavy rainfall. Researchers believe shifting winds, rather than drought, caused the lakes to vanish. The finding raises concerns that future climate-driven wind changes could again threaten the sacred lakes known as the Eyes of K'gari.
