Despite being “dry” for many years near their differently colorful waterborne neighbors, the inactive ledges of Mammoth Hot Spring still stand sharp yet ghostly, resplendently frozen in time with travertine textures and mineral stains from the time when they accumulated layers under hot water flow. In the background, even older ledges show signs of erosion, having lost many of their staining minerals to slow dissolution by rain and melting snow.
