Petrified Forest of José de Ormachea, Natural monument in Sarmiento, Chubut Province, Argentina.
The petrified forest spans 1,880 hectares across the Patagonian steppe, containing fossilized tree trunks from ancient coniferous species.
Scientists discovered this geological formation in 1927, leading to its designation as a protected natural area through Provincial Law 2161 in 1973.
The interpretation center displays paleontological and archaeological artifacts that document the geological and biological evolution of the region.
The forest opens from 10:00 AM to 6:00 PM during low season and 9:00 AM to 7:00 PM in high season, with guided trails lasting one hour.
The forest contains tree specimens from 65 million years ago, when the region experienced a warm climate with primitive ferns and conifers along riverbanks.
