Yellowstone photos series : Mammoth Hot Springs

Yellowstone National Park preserves the most extraordinary collection of hot springs, geysers, mudpots, and fumaroles on Earth. More than 10,000 hydrothermal features are found here, of which more than 500 are geysers. Mammoth Hot Springs are pools of hydrothermally heated water. Hot springs are the most common hydrothermal features in Yellowstone. Beginning as rain at the surface, the water of a hot spring seeps through the bedrock underlying Yellowstone and becomes superheated by the Yellowstone magmatic system.

Many of the bright colours found in Yellowstone’s hydrothermal basins come from thermophiles—microorganisms that thrive in hot temperatures. An abundance of individual microorganisms grouped together appear as masses of colour. This explains the bright orange, blue and white you can find on Mammoth :).

The hike around the terraces is not hard but features a few stairs and almost no shade at all. I would recommend to go before 10am to avoid the heat and the big crowds.
