Alien-Looking Landscapes You Can Actually Visit on Earth

18. Fly Geyser, Nevada, USA – A Psychedelic Fountain of Fire and Water

Hidden in the Nevada desert, Fly Geyser is an accidental man-made marvel that has evolved into something straight out of a fantasy world. This geothermal geyser was created when well-drilling accidentally hit a thermal pocket, leading to a continuous eruption of boiling water. Over decades, mineral deposits have formed a vibrant, cone-shaped mound covered in brilliant hues of green, red, and orange due to thermophilic algae. The result? A glowing, steaming, living alien structure in the middle of the barren desert.
