Fly Geyser is a fascinating and unique geothermal geyser located in the Black Rock Desert of Nevada, United States. The geyser is notable for its vibrant and multi-colored appearance, which is a result of the minerals present in the geothermal water that flows out of the geyser. Fly Geyser was formed accidentally in 1916 during an attempt to drill a well for irrigation purposes. The drilling hit a geothermal pocket of water that was heated by volcanic activity deep below the surface, which led to the formation of the geyser. Over time, the geyser has grown in size and now stands over five feet tall. The mineral-rich water that flows out of the geyser creates a series of terraces and pools, which are surrounded by colorful formations of red, green, and yellow. These vibrant colors are the result of thermophilic algae that thrive in the hot and mineral-rich environment.
