|Jupiter Terrace, Yellowstone Park|
Jupiter Terrace is no longer the colorful attraction it once was. Many of the terraces at Yellowstone's Mammoth Hots Springs go through intermittent cycles of activity. When active, the terraces grow as calcium and carbonate brought to the surface from underground springs combine on the surface to form travertine in step-like formations. Brightly colored mats of algae thrive in the hot water of active springs. But as activity ceases, the colors give way to the barren gray of weathered travertine.
