Valley of Fire State Park is the oldest state park in Nevada, USA and was designated as a National Natural Landmark in 1968. It covers an area of almost 42,000 acres (17,000 ha) and was dedicated in 1935. It derives its name from red sandstone formations, formed from great shifting sand dunes during the age of dinosaurs. These features, which are the centerpiece of the park's attractions, often appear to be on fire when reflecting the sun's rays.
Valley of Fire is located 50 miles (80 km) northeast of Las Vegas, at an elevation between 2,000–2,600 feet (610–790 m). It abuts the Lake Mead National Recreation Area at the Virgin River confluence. It lies in a 4 by 6 mi (6.4 by 9.7 km) basin.
Complex uplifting and faulting of the region, followed by extensive erosion, have created the present landscape. The rough floor and jagged walls of the park contain brilliant formations of eroded sandstone and sand dunes more than 150 million years old. Other important rock formations include limestones, shales, and conglomerates.
