description Roaring Mountain Overview
Roaring Mountain is an acid-sulfate thermal area in Yellowstone National Park, located beside the road between Norris Geyser Basin and Mammoth Hot Springs. Its pale, altered slope contains numerous fumaroles and steam vents created as volcanic heat drives gases and water through fractured ground. The mountain received its name because its fumaroles were reportedly loud enough in the early twentieth century to be heard from miles away, although their activity and sound have since diminished.
