Fumarole Butte is an impressive geological formation located in the Lower Sevier watershed of Utah. It was created by a volcanic eruption that occurred over 10 million years ago. The butte is made up of welded volcanic tuff, which is a type of rock formed by the consolidation of volcanic ash and debris. The tuff is layered and has a texture that resembles a honeycomb. The butte is also home to several fumaroles, which are openings in the earth's crust that emit steam and other gases. The fumaroles are a result of the geothermal activity that still exists in the area.
