The hole, or vent, of Old Faithful geyser in Yellowstone National Park has a diameter of approximately 10-12 feet (3-4 meters). This opening is where the geothermal activity occurs, allowing water and steam to erupt periodically. The geyser typically erupts every 90 minutes, shooting water up to 180 feet (55 meters) into the air. The size of the vent contributes to its ability to produce these dramatic eruptions.
