Old Faithful Geyser

Discovered in 1870 by the Washburn Expedition, Old Faithful geyser was named for its frequent eruptions — which number more than a million since Yellowstone became the world’s first national park in 1872. Old Faithful erupts about every 92 minutes, shooting water 135 feet into the air on average. Like most of theYellowstone's geysers, Old Faithful gets its water from deep inside the earth. Snow and rainwater reach depths of about 10,000 feet below the ground, where it is heated by magma and forced back up through the surface.

Castle Geyser
Castle Geyser is attracts a crowd because of its energy. 15 minutes into an eruption, Castle goes into a raucous steam phase that roars like a train. Erupting every 11-13 hours, Castle shoots water 70-80 feet into the air from one of the largest cones in the Upper Geyser Basin — over 30 feet tall.

Riverside Geyser
Riverside Geyser is unique because it erupts over a river — literally. Every six hours, Riverside shoots water about 80 feet into the air at a 60-degree angle across the Firehole River. Each eruption lasts about 20 minutes.
