The Fire Wave is a natural sandstone formation in Valley of Fire State Park in Nevada, which resembles an ocean wave with swirling red, white, and pink sandstone patterns.
This occurs when different layers of rock are eroded at different rates. In the case of the Fire Wave, the different layers of rock are made up of different minerals, which have different resistance to erosion. The red and pink layers are made up of iron oxide, which is more resistant to erosion than the white layer. This is why the red and pink layers have been sculpted into waves, while the white layer remains relatively flat.
