This hissing mountain of steam is the only thing like it in Yellowstone. Roaring Mountain is a barren hillside of thermal features called fumaroles. It got its name from the loud hissing and roaring that it makes due to thermal activity and could be heard miles away in the days of its discovery. Nowadays the roaring has quieted a bit but can still be heard if you listen carefully. There are no trees on the most active parts of Roaring Mountain due to the intense heat and gases that emminate through its vents. Its slopes are inhospitable to all but the toughest microorgansims. This unique mountain is in one of the hottest parts of Yellowstone National Park.
Roaring Mountain is formed of rhyolite, a volcanic rock that contains 70-75% silica, which combined with the thermal action gives it this white appearance. Looks like snow but isn't.
So many wonders in this special ecosystem.
