Mammoth Hot Springs

Mammoth is the park's headquarters and is located at the northwest corner of the park. It is easily accessed via the north entrance from nearby Gardiner, Montana. Originally Yellowstone was administered by the US Army until 1918, when the National Park Service was formed and took over the task of administering Yellowstone. The original army parade grounds, barracks, and offices remain and are now utilized by the park service. The biggest feature that attracts visitors to Mammoth are it's thermal terraces. Thermal features come in many shapes and forms. The ever popular geysers are mostly found in the Old Faithful, Norris, and West Thumb areas while bubbling mud pots and fumaroles are found in the Fountain Paint Pots area. The Mammoth area doesn't have these but it's hot springs hang on the steep slopes towering over the village and have built up travertine terraces that are unrivaled anywhere else. These terraces took many years to build themselves to this height but it's easy to see the changes in them from year to year. The mineral laden boiling water rises to the surface, depositing the mineral in pools, building the terraces. Eventually this water cascades down the sides and forms a castle like structure with many levels. Some will dry up while new ones appear in different locations. Some previously dormant springs will return to life many years later as the subterranean plumbing constantly reroutes itself. In addition, the Mammoth area is a very popular gathering spot in the fall for the northern range elk herd. The bugling of bull elk echoes throughout the surrounding hills as they gather their harems. This is a popular gathering spot for tourists during the fall as they gather to view the show that the elk put on. Leaving Mammoth, one can drive south through Golden Gate towards the Norris area or head east over the Blacktail Plateau to the Tower-Roosevelt Area.

Mammoth Village

This view of Mammoth Village was taken from on top of Main Terrace. It shows the village area as surrounded by the mountains around it. The historic Mammoth Hotel can be seem in the right-top corner with it's cream colored columns. The many other building in the area are all park service building that were built and formerly occupied by the US army, who managed the park prior to 1918, when the National Park Service was formed.

Bighorn Sheep

Bighorn Sheep frequent steep rocky slopes where they can easily evade predators. Their hoves are specially designed for both traction and durability in the sharp rocks and shale.

Liberty Cap

In Mammoth Village, near the base of the lower terraces is Liberty Cap. Liberty Cap is a dormant geyser cone. At one time the cone spewed forth hot water, but as it did the cone grew larger, eventually clogging the orifice. It now stands as a tower of solid geyserite and derives it's name from a style of hat that was popular during the American Revolution.

Minerva Terrace

The terraces are constantly in change. In 1991 Minerva Terrace was vibrantly flowing and it's colorful mineral water was cascading down each layer. In 2003 these terraces had all but dried up. Minerva Terrace is found at the base of the cliff where the larger Jupiter and Main Terraces are found resting up top.

Main Terrace

Main Terrace was the feature event in the early 1900s. Since the 1960s it has pretty much dried up and the water diverted to other areas. Recently the Main Terrace has begun a resurgence on it's southern flank. The steaming pools in this section have overtaken the original boardwalks and are now host to a variety of algae.

Mound Geyser

Hidden behind Main Terrace is Mound Geyser. While originally a geyser, with cyclic eruptions, it is now a steady flowing spring. It steaming hot waters flowing steadily down it's face reveal the heavy iron content as well as calcium in it's waters.

Resting Elk

During the fall rut bull elk expend a great deal of energy gathering their harems. In the Mammoth area many bulls can be seen resting in the public areas. It's important to give these animals some breathing room because they can get irritated easily and have been know to charge both people and vehicles with their sharp antlers.
