The province of La Rioja, northwestern Argentina, is bounded by the
province of Catamarca, on the north; the
provinces of Catamarca and Córdoba, on the east; the
province of San Luis, on the south; and the province of San Juan and the Republic of Chile, on the west.
It has an area of 89,680 square kilometers (2.4% of the country area), marked
by sharp contrasts within the provincial relief. From the western plains to the Andes foothills, stretches
one of the most arid ambients of Argentina. On the west extreme is the Frontal cordillera, with
peaks exceeding 1,219 feet. Eastward, the great altitude of the Famatina Sierra allows humidity
condensation in the form of either rain or snow, the fusion of which feeds a series of rivers that
irrigate the greatest oasis in the province: Chilecito. Annual precipitation amounts to 300 mm in the eastern area.
