For the second year running, petroglyphs dating back some 2,000 years have reappeared at the Ponta das Lajes Archaeological Site due to the record drought of the Rio Negro in 2024 (the biggest ever recorded). The figures are carved in an area of about 150,000 m², and are submerged during the flood period and may remain so for years, depending on the strength of the next floods, protected from human action such as vandalism and destruction of the area. The engravings are important vestiges of the pre-colonial period, where it is estimated that there were indigenous settlements in the region, with characteristics found in other sites in the state of Amazonas.
