Geothermal Areas are specific locations of geothermal (high-heat) potential of the groundwater (e.g., Coso Geothermal Area). The base set of geothermal areas used in this database came from the 253 geothermal areas identified by the USGS in their 2008 Resource Assessment.
Additional geothermal areas were added, as needed, based on a literature search and on projects listed in the 2011 database of funded projects.
