Sawmill Geyser in the Upper Geyser Basin erupts intermittently, sometimes for hours at a time. It is a fountain-type geyser, erupting up through a pool of water. Pulses of hot water punch up 20 feet or more in the air with deep "thump" and "poosh" sounds. The tinkle of glassy round drops of water falling back onto the surrounding rock creates a second song. These eruptions spin and scatter water all around and regularly wet the nearby boardwalk.
