Mammoth Hot Springs & Geyser Basin in Yellowstone/July 2008

These pictures are taken at Mammoth Hot Springs.

Surface water seeps underground, is heated by a deep source of magma, and rises as superheated water. Hot Springs have no constrictions, so water rises, cools, and sinks. The small amount of water in fumaroles flashes into steam before reaching the surface. Mudpots are acidic hot springs with limited water.

These are midway, lower and upper Geyser Basin. There are many of these through out the park and on our way to Mammoth Hot Springs.
