Yellowstone National Park
Geysers
These are a selection of pictures taken of various geysers seen along the road and throughout the park. Not all geysers erupt with the frequency of Sawmill Geyser (every 20 seconds) or Old Faithful (about every 93 minutes). The frequency of many of the geysers varies from every few days to as long as only a couple times in a year. Some have become inactive because of shifts in the thermal activity below the surface.
