The Old Faithful: A Spectacular Cone Geyser

Old Faithful, located in Yellowstone National Park, is a prime example of a cone geyser. It is not just any geyser, but a spectacular natural phenomenon that draws millions of visitors each year. Its predictability and impressive eruptions make it a must-see spectacle.

Cone geysers, like Old Faithful, are characterized by their distinctive conical shape. The buildup of mineral deposits from the water’s continuous eruption creates this cone shape over time. This distinguishes them from other types of geysers, such as fountain geysers and steamboat geysers.

The Mechanism of Eruption

One of the key features of cone geysers is the manner in which they erupt. The eruptions are generally powerful and occur at regular intervals. The underground reservoir of water heats up from geothermal activity, causing immense pressure to build up. Eventually, this pressure is released through a narrow vent in the cone, propelling a column of boiling water and steam skyward.

Old Faithful, specifically, erupts like clockwork approximately every 60-90 minutes, reaching heights of 106 to 184 feet. This predictability has made it a favorite among visitors and scientists alike, allowing researchers to study its behavior extensively.

The Geological Significance

Aside from its visual splendor, Old Faithful’s eruptions offer insights into the geological forces at work beneath the Earth’s surface. The monitoring and study of cone geysers like Old Faithful contribute significantly to our understanding of geothermal activity and the dynamics of volcanic landscapes.

Misconceptions About Old Faithful’s Geyser Type

Fountain geyser

Many people mistakenly believe that Old Faithful is a fountain geyser, which is understandable given its impressive display of water shooting high into the air. However, the defining feature of a fountain geyser is a continuous spray of water, not the intermittent eruptions that Old Faithful is known for. Fountain geysers typically have irregular, non-cylindrical shapes, whereas Old Faithful’s eruptions are characterized by a tall, narrow column of water, making it a cone geyser instead.

Steam vent

Another misconception is that Old Faithful is a steam vent, but this is not accurate. While steam vents release steam and gases from the Earth’s crust without ejecting water, Old Faithful’s eruptions involve the explosive release of both water and steam, distinguishing it from a typical steam vent. The spectacle of Old Faithful is not just the billowing steam, but the forceful expulsion of water, characteristic of a true cone geyser.

Pool geyser

Some may also mistakenly classify Old Faithful as a pool geyser, assuming that its eruptions originate from a pool of water. However, a pool geyser is characterized by a quiet, continuous overflow of water from a pool, whereas Old Faithful’s eruptions involve a buildup of pressure in an underground reservoir that propels water upward in a dramatic display. Thus, Old Faithful’s type is correctly identified as a cone geyser, distinct from the characteristics of a pool geyser.


In summary, Old Faithful is what we know as a cone geyser, which is known for its towering bursts of hot water and steam that have been a spectacle for visitors at Yellowstone National Park for decades.

Old Faithful is a prime example of a cone geyser, and its predictable eruptions have made it one of the most famous and studied geysers in the world. The geological wonders of our planet never cease to amaze.
