Jaramillo Petrified Forests National Park

The Jaramillo Petrified Forest National Park is a protected area of petrified forest located in the Deseado Department, in the northeast of Santa Cruz Province, Argentina. Formerly part of the site was a natural monument, established in 1954 and known as the Petrified Forest Natural Monument, covering about 13,700 hectares. This area has remnants of a forest preserved in stone, that had been growing on the site before the upthrust of the Andes some 150 million years ago. In December 2012, further land was added and the protected area was reclassified as a national park with a total area of 78,543 hectares.
