Formed from great shifting sand dunes during the age of dinosaurs, 150 million years ago. Complex uplifting and faulting of the region, followed by extensive erosion, have created the present landscape. Other important rock formations include limestones, shales, and conglomerates. Prehistoric users of the Valley of Fire included the Basket Maker people and later the Anasazi Pueblo farmers from the nearby fertile Moapa Valley. The span of approximate occupation has been dated from 300 B.C. to 1150 A.D.
In 1966, Hollywood filmed a classic Western in this park. The natural splendors along this hike might inspire your own lines worthy of a Hollywood script. Here, you’ll see a slot canyon (at points only 18 inches wide and 80 feet deep), a natural arch, multicolored sandstone, and interesting patterns of erosion that have created sculptured forms around the trail.
