Thermal Springs List for the United States

This list of United States thermal spring locations and temperatures and accompanying maps have been compiled in the course of preparing the maps: (1) Geothermal Energy Resources of the Western United States by National Geophysical and Solar-Terrestrial Data Center, National Oceanic and Atmospheric Administration (NOAA) (Grim, 1977); (2) Geothermal Energy in the Western United States and Geothermal Energy in Alaska and Hawaii in the U.S. Geological Survey (USCS) Assessment of Geothermal Resources of the United States-7978 (Muffler, 1979); and (3) State maps in press and preparation for the State Coupled Resource Assessment Program, U.S. Department of Energy, Division of Geothermal Energy (DOE/DGE). The list is a compilation of compilations, mainly from Waring's (1965) monumental Thermal Springs of the United States and Other Countries of the World; a Summary, USGS CEOTHERM computer file of thermal spring and well data, and currently active DOE/DGE-sponsored thermai data collection by State agencies and other organizations.

The compilation (table 1) has 1,702 thermal spring locations in 23 of the 50 States, arranged alphabetically by State (Postal Service abbreviation) and degrees of latitude and longitude within the State. It shows spring name; surface temperature in degrees Fahrenheit and degrees Celsius; USGS Professional Paper 492 number; USCS Circular 790 number; NOAA number, north to south on each degree of latitude and longitude of the listed USGS 1:250,000-scale (AMS) map; and the USCS topographic map coverage, 1:63360- or 1:62500-scale (15-minute) or 1:24000-scale (7.5-minute) quadrangle.

Table 2 is an alphabetized list showing only the spring name and the State in which it is located. Unnamed springs are omitted.

The list includes natural surface hydrothermal features: springs, pools, mud pots, mud volcanoes, geysers, fumaroles, and steam vents at temperatures of 2OoC (68OF) or greater. It does not include wells or mines, except at sites where they supplement or replace natural vents presently or recently active, or, in some places, where orifices are not distinguishable as natural or artificial.

Elevation was reported as the range 1,010 - 4,401. The maximum elevation value was entered into the surface elevation field.
