Insider Guide to Yellowstone
The dominant rock in this area is limestone, while rhyolite dominates in the rest of Yellowstone. Limestone is an essential ingredient in the formation of terraces. Hot water with dissolved carbon dioxide makes a solution of weak carbonic acid. The acid dissolves calcium carbonate, the primary mineral in limestone. The calcium carbonate is then deposited to form terraces of Mammoth Hot Springs.
Observe the colors at Mammoth Hot Springs, which are created by thermophiles (heat-loving microorganisms).
Mammoth Hot Springs are composed of the upper loop, accessible by car, and the lower loop, only accessible on foot. If you are visiting in the summer, be prepared for heat in this area because of hot springs. There is virtually no shade on the Lower Terraces boardwalk and limited shade on the Upper Terraces, so wear plenty of sunscreen and a hat.
Some of the must-see attractions include Minerva Terrace, Palette Spring and Liberty Cap.
