      The Northwest region (Mammoth-Gallatin region) is a land of extremes. Elevations within the Mammoth area range from about 5,000 to 11,000 feet, with the lowest (in the park) near the Yellowstone River and the highest at Electric Peak, just miles away. The Gallatin Range, which sticks it thumb into Yellowstone for 20 miles from the north, includes about 19 peaks. Of these. Electric Peak (10,992 feet) dominates the northern end, and Mount Holmes (10,336 feet) marks the southern end.

      The Gallatin Mountains are an uplifted range composed of stratified shales, limestones and sandstones dipping slightly northward. The composition of these limestones and the presence of oceanic fossils testifies that they once were part of large inland seas. Rugosa-or horn-corals, bryozoans and clam-shaped fossils are embedded on the slopes of these mountains.

      The influence of limestone in the Mammoth area also has changed the makeup of the hydrothermal features. Elsewhere in the park, the surrounding rock is composed of silica dioxide, an essential element in the formation of geysers. But, here, the presence of calcium carbonate produces the unusual travertine terraces of Mammoth.
