Mammoth Hot Springs is a large hot spring complex on a travertine hill in Yellowstone National Park adjacent to Fort Yellowstone and Mammoth Hot Springs Historical District. It was created for thousands of years as the hot water of the springs cooled and stored calcium carbonate (more than two tons flow into Mammoth every day in a solution). Due to the amount of geothermal ventilation, the travertine is growing. Although these springs are outside the caldera boundary, their energy has been attributed to the same magmatic system that drives other Yellowstone geothermal regions.
The hot water that feeds Mammoth comes from the Norris Geyser Basin after walking underground through a fault line that runs through limestone and roughly parallels the Norris-to-Mammoth path. The limestone of the rock formations along the fracture is a source of calcium carbonate. The shallow circulation along these corridors allows the superheating water of Norris to become slightly cool before it appears in Mammoth, generally around 170 ° F (80 ° C). The algae that live in warm pools have shades of brown, orange, red, and green.
The thermal activity here is wide both from time to time and distance. Thermal flow shows a lot of variability with some variations that occur during the period from decade to day. The Mountain Terraces in Mammoth Hot Springs are the largest known deposit-springs in the world. The most famous feature in the spring is Minerva Terrace, a series of travertine terraces. Terraces have been deposited by springs for years but, due to recent small earthquake activity, the spring vents have shifted, leaving the terrace dry.
The Mammoth Terrace runs all the way from the hillside, across the Ground Parade, and down into the Boiling River. The Mammoth Hotel, as well as all Fort Yellowstone, is built on an old terrace formation known as the Terrace Hotel. There was some concern when construction began in 1891 on the site of the castle that the perforated ground would not support the weight of the building. Some large (fenced) sink holes can be seen at the Ground Parade. This area has been thermally active for several thousand years.
The Mammoth region shows much evidence of glacial activity from Pinedale Glaciation. The summit of the Terrace Mountain is covered with glacial until, thus dating a travertine formation there earlier than the end of Pinedale Glaciation. Some thermal kames, including Capitol Hill and Dude Hill, are the main features of the Mammoth Village area. The marginal ice-flow layer becomes evident in the small and narrow valley where Floating Island Lake and Phantom Lake are found. At Gardner Canyon, one can see the old gravel layers on the Gardner River covered by un-sorted glacial.
