Kavir National Park is a protected ecological zone in northern Iran. It has an area of 4,000 square kilometers (1,500 mile²). The park is located 120 kilometers south of Tehran and 100 kilometers east of Qom, and it sits on the western end of one of Iran's two major deserts, the Dasht-e Kavir (Great Salt Desert). Siahkuh (Black Mountain), a large, semi-circular rock outcropping sits in roughly the park's center.
