Roaring Mountain (8,152 feet (2,485 m)) is in Yellowstone National Park in the U.S. state of Wyoming. Roaring Mountain was named for the numerous fumaroles on the western slope of the peak which during the early 1900s were loud enough to be heard for several miles. Roaring Mountain is 5 miles (8.0 km) north of Norris Geyser Basin and south of Obsidian Cliff and is easily seen from park roads.
