Atlatl Rock Valley of Fire Nevada .

Valley of Fire State Park is the oldest state park in Nevada, USA. It covers an area of 34,880 acres (14,120 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,-
