Created in 1970, it covers an area of 5,030 hectares (12,429 acres)[1] and includes part of the Pali-Aike Volcanic Field.

[3] It includes native flora and fauna, with some species being exclusive to the region, not being found anywhere else in the world.

The stone tools from the cave are dated to around 11,000 years BP, and are among the oldest in South America.

In 1998, the Pali Aike and Fell's Caves were jointly proposed to UNESCO as World Heritage Sites.
