WATCH: Drought exposes ancient Amazon rock carvings

Ancient rock carvings of human faces and other shapes have appeared along the Amazon River amid a historic drought causing record-low water levels.

The engravings — estimated to be between 1,000 to 2,000 years old — were found in Ponto das Lajes, an area on the Amazon where the Rio Negro and Solimoes rivers meet.

While the carvings were first partially exposed in 2010, this year's drought is more severe, revealing a broader range of carvings.

The drought has been exacerbated by climate change and deforestation.
