The state park derives its name from red sandstone formations, the Aztec Sandstone, which formed from shifting sand dunes 150 million years ago. These features, which are the centerpiece of the park’s attractions, often appear to be on fire when reflecting the sun’s rays.
Prehistoric inhabitants of the Valley of Fire included the Ancestral Puebloans, also known as the Anasazi, who were farmers from the nearby fertile Moapa Valley. Their approximate span of occupation has been dated from 300 BC to 1150 AD. Their visits probably involved hunting, food gathering, and religious ceremonies, although scarcity of water would have limited their stay. Fine examples of rock art (petroglyphs) left by these ancient peoples can be found at several sites within the park.
