Hot water travels underground from Norris Geyser Basin through a fault line running through limestone, cooling slightly before surfacing here at around 170°F. That journey deposits more than two tons of calcium carbonate daily, building the travertine terraces that define Mammoth Hot Springs. Terrace Mountain is the largest known carbonate-depositing spring in the world. Algae tint the travertine brown, orange, red, and green. The most famous feature, Minerva Terrace, has gone dry after a spring vent shifted following minor earthquake activity — the geology here answering to no one.
