Mammoth Hot Springs is a massive complex of hot springs in Yellowstone National Park, known for its stunning travertine terraces formed by mineral deposits. The hot water comes from Norris Geyser Basin and flows through limestone before surfacing at Mammoth, creating colorful algae-covered pools. The area shows evidence of glacial activity and features various named thermal springs and terraces. Despite recent shifts in the spring vent, Mammoth remains a popular destination for visitors seeking unique geothermal wonders in the park.
