The Mammoth Hot Springs Terraces are constantly changing, with formations growing in different directions. The water flows and creates a beautiful living sculpture.
The step-like terraces form as heated water moves along the Morris-Mammoth Fault. The hot water carries dissolved calcium and bicarbonate to the surface of the terraces where pressure lessens. Carbon dioxide then escapes as gas and the carbonate combines with calcium to precipitate as travertine. Springs which were active one to five years ago may be dry and lifeless now, yet activity may later resume. Along with changes of thermal activity come changes in color. Fresh travertine is bright white in color and as it weathers it changes to gray. Bright colored cyanobacteria and algae mats which were dependent upon a stable temperature and a flow of water also change as the microorganisms die creating a stark, bleak landscape.
Everyday is a reminder that God exist. :)
