Yellowstone National Park

Terrace Mountain at Mammoth Hot Springs is the largest known carbonate-depositing spring in the world. The most
famous feature at the springs is the Minerva Terrace, a series of travertine terraces. The terraces have been deposited
by the spring over many years but, due to recent minor earthquake activity, the spring vent has shifted, rendering
the terraces dry.

(R) Rustic Falls is located at the entrance to Golden Gate Canyon

The name comes from the color of the rocks, some of which is due to native lichens. Golden Gate Canyon was
named in 1883-84 when the first stagecoach road was built through it. It was most likely named by someone
on the construction crew or by an early tour operator. The bridge was originally built in 1885 of wood. The first
concrete bridge was built in 1901, widened in 1934, and totally rebuilt in 1977.

flanked by long frame wings containing guest rooms. The inn is a prime example of the "Golden Age" of

of the few log hotels still standing in the United States. Besides of the Inn, there are Old Faithful Lodge and
Old Faithful Snow Lodge, which is open during the winter season, at a different location.
