The hot springs and seeps are located in the
Sevier Desert on
Fumarole Butte which is a
basaltic andesite type of
shield volcano from the Quaternary period, overlaying basalt and
rhyolite. The hot water emerges from a
travertine and
alluvial mound (sometimes described as a
tufa mound) that flank the eastern side of the basalt lava formation. The area is fenced, but accessible, and used primarily by locals. There are a series of concrete soaking tubs constructed west of the spring heads. ==See also==
