Sawmill Geyser, named for the whirring sound it makes during its eruption, is a geyser in Yellowstone National Park, Wyoming, USA. The geyser was named by Antoine Schoenborn of the Hayden Geological Survey of 1871.
Sawmill is the largest geyser in the Sawmill Complex, a region of geothermal features located in Upper Geyser Basin approximately 10 feet off the path.[2] This geyser has an irregular pattern of eruption due to the structure underground plumbing of the geysers, but has a delay around 1 to 3 hours between eruptions. It tends to erupt after Spasmodic Geyser, but only if Penta Geyser does not erupt first. If Penta Geyser erupts before Sawmill gets a chance, Sawmill is cut off from water, and cannot erupt until Spasmodic erupts again. Another eruption indicator is when Sawmill fills with the rest of the geyser's water in the Sawmill Complex or starts to overflow, bubbles tend to rise to the surface. This indicates that an eruption is near. Sawmill drains after its eruptions, and if it had a large eruption prior, unusual behavior can occur in other geysers in the area.
