Mammoth Hot Springs is one of the many amazing places within Yellowstone National Park.  And, it is always different each time you visit.  What was once a beautiful display of color and water, time and buildup of deposits changes the flow of hot spring water, and the old display dies and becomes pure white, and new displays form.  Hot Springs are thus ever-changing.

Other areas of the park include Yosemite Valley and Falls, and Old Faithful, amongst others.
