Orange Spring Mound
Hot
water flows over the mound after bubbling through several vents along the
tops.
Heat
dwelling bacteria and algae grow abundantly in Orange Spring Mound's water
creating tapestries of "living color."

Above the ground, the water begins to cool and evaporate. Gases are
released and water pressure decreases. Orange Spring
Mound gradually grows as water flows over it, depositing calcium carbonate,
or travertine.

Under great pressure, the water percolates upward through buried limestone, dissolving
a mineral called calcium carbonate.
