#7: Fly Geyser, Nevada, USA
Fly Geyser looks like a tiny alien volcano that wandered into the Nevada desert and decided to stay. It formed accidentally after geothermal drilling, and mineral deposits slowly built colorful cones around the constant flow of hot water. Algae and thermophilic organisms add greens, reds, and oranges to the surface. It is not ancient wilderness in the pure sense. It is a human mistake that nature redecorated spectacularly.
