Hot Springs
From Open Energy Information
Hot Springs:
A naturally occurring spring of hot water, heated by geothermal processes in the subsurface, and typically having a temperature greater than 37°C.
Modern Geothermal Features
Typical list of modern geothermal features
Hot springs occur where geothermally heated waters naturally flow out of the surface of the Earth. Hot springs may deposit minerals and spectacular features such as terraces of travertine or silica, tufa mounds, and sulfuric deposits.
