Regarded as ”the Oil Capital”, Rincón de los Sauces lies along Colorado River and its soil provides the resource that supplies the country’s energy industry.
Its location determines the semiarid climate, showing the characteristics of a desert area with scarce rainfalls and low humidity records. Summers are extremely hot, with temperatures reaching 40ºC. The flora is very rich, with a wide range of indigenous vegetation that is unique in the province as well as in the rest of the country. Some of those indigenous species are considered to offer medicinal and healing powers: jarilla, sampa, vidriera, matasevo, Azorella, Chuquiraga, and argylia robusta among others.
Native fauna that prevails in the area includes: guanacos, foxes, skunks, armadillos, maras (Patagonian hare), armadillos, tortoise, inambú, macá, Neotropic cormorant and ñanco.

Rincon de los Sauces History
In the ’60s, the state company YPF began its oil exploration activities in the area, hitting oil in 1968 in Puesto Hernández. Over the years, this place became one of the main oilfields in the country.
Oil discovery led to a rapid change in the area, and the old oil campsite turned into a town, which was officially founded on December 20, 1971.

Auca Mahuida Ghost Town
89 km southwards of Rincón de los Sauces, time seems to have stood still on August 22, 1947. Auca Mahuida used to be an asphaltite mine operated by the homonymous company, which had to close down after an explosion that left 15 miners buried in the mine’s underground galleries.
In its heyday, in 1947, around 1500 people lived in the town, although today only a group of about 20 houses remain. But no inhabitants. Auca Mahuida was once the largest town in the region, when Añelo was no more than a spot and Rincón de los Sauces didn’t exist yet.
In the underground mine, 105 m deep and 350 m long, 80 trucks of asphaltite were produced per day, along tunnels at different levels of depth.
Abandoned houses and buildings can be found all along the avenue, some of them with their roofs, plaster and adobe bricks still intact, some of them totally run-down. The former general store, the infirmary, the butcher’s shop and the police station with its jail lie on the hillside, facing what used to be the offices of Auca Mahuida Company, which operated La Escondida mine.
