Ischigualasto is a geological formation and a natural park associated with it in the province of San Juan, north-western Argentina, near the border with Chile. The Ischigualasto Provincial Park is located in the north-east of the province, and its northern border is the Talampaya National Park, in La Rioja, both of which belong to the same geological formation and were named UNESCO World Heritage Sites in 2000. It has an area of 603.7 km2 (233 sq mi), most of them within the Valle Fértil Department, with a minor part in the Jachal Department of San Juan, at an altitude of about 1,300 m (4,265 ft) above mean sea level. The park is part of the western border of the Pampean Hills, and it features typical desert vegetation (bushes, cacti and some trees) which covers between 10 and 20% of the area. The climate is very dry, with rainfall mostly during the summer, and temperature extremes (minimum -10 °C, maximum 45 °C). (Full article...)
