Informations supplémentaires

Mammoth Hot Springs is a large complex of hot springs on a hill of travertine adjacent to Fort Yellowstone it was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate. Over two tons flow into Mammoth each day in a solution. Because of the huge amount of geothermal vents, the travertine deposits continue to grow. These springs lie outside the caldera boundary, as a result the temperature of the water is lower, a maximum of 165 °F. This is why there are no geysers and the deposit has reached an overall thickness of roughly 246 feet and an expansion of more than 1.5 square miles since the first springs started flowing nearly 8800 years ago.
