Minerva Terrace in Mammoth Hot Springs, Wyoming

Mammoth Hot Springs is one of the most popular natural wonders in a park full of them. Minerva Terrace has been dry during the past few years thanks to recent earthquake activity, but when the geothermal springs are flowing, the water is continually reshaping the area, drawing limestone up from the ground and depositing it on the surface to form these pale stone formations. Colors on the travertine come from algae living in the warm water.

Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park adjacent to Fort Yellowstone and the Mammoth Hot Springs Historic District. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate. Because of the huge amount of geothermal vents, travertine flourishes. Although these springs lie outside the caldera boundary, their energy has been attributed to the same magmatic system that fuels other Yellowstone geothermal areas.
