Sarmiento Department, Argentina

Petrified Forest of José de Ormachea

An ancient forest of the Paleocene Age turned to stone. 

65 Million years ago a forest was destroyed by volcanic eruptions. Preserved as fossils today, the Petrified Forest of José de Ormachea near Sarmiento is now a natural reserve showcasing the ancient trees.

Although very rare, other petrified forests can be found in the United States in California, and Arizona, elsewhere in Argentina, and on the island of Lesbos, Greece.
