Ghost on the Terrace

Several thousand pounds of calcium carbonate, carried in solution from the hot springs that bubble up through thick limestone, are deposited onto the enormous terraces each day along the terraces at Mammoth Hot Springs in Yellowstone National Park. As the terrace complex spreads and grows, surrounding vegetation is overtaken. In this photo several dead trees are seen embedded in calcium carbonate, with steaming water flowing around them, a ghostly scene.
