Cerro del Fuerte is located in the Central Precordillera of San Juan province, about 25 Km northeast of Jáchal city and 5 Km south of the Huaco river. It is directly accessible from national route 40, which passes a few kilometers of north of outcrops.
Cerro del Fuerte is a key geological and paleontological site in the eastern Precordillera of San Juan Province, about 20 Km southeast of Jáchal, and is part of the La Chilca formation. It is world-famous for its Lower Paleozoic (Ordovician and Silurian) outcrops dating back more than 430 millon years. It contains very complete stratigraphic profiles of Paleozoic rocks and it stands out for its fossils rich findings of graptolites, brachiopods, and conodonts that allow us to understand early marine life in South America.
