Rock patterns in Kaolin Wash, Valley of Fire State Park, near Moapa Valley, Nevada, USA. A great 3.5-mile "spectacle loop" (with 450 feet of gain and loss) starts at Park Turnout #3, goes to the Fire Wave, proceeds along the Seven Wonders Trail through Kaolin Wash, completes the White Domes Trail Loop back to the movie set remains, repeats a quarter mile of Kaolin Wash, turns north on Seven Wonders Trail past Thunderstorm Arch, and returns to Park Turnout #3. Starting more than 150 million years ago, great shifting sand dunes during the age of dinosaurs were compressed, uplifting, faulted, and eroded to form the park's fiery red sandstone formations.
