3. The Lost City Is A Collection Of Hydrothermal Vents
You’ve probably heard of Old Faithful, famous geysers at Yellowstone National Park. It is a hydrothermal vent, meaning that it is a fissure in the surface of the earth from which water and other subterranean compounds erupt. The Lost City is an underwater system of hydrothermal vents.
The Lost City is located at the base of Atlantis Massif, a large mountain in the Mid-Atlantic Range that is about the size of Mount Ranier in Washington. The hydrothermal vents present the most extreme underwater environment that we currently know of; they test the limits of where life can exist.
