These layer files contain the symbology for portrayal of geothermal features in ArcMap. For the Borehole Temperatures and thermal springs, the color ramp ranges from green (cool) to red (hot) for each feature. For the active faults legend, the FGDC symbology was used (with additions further specifying activity during the early Quaternary). For the volcanic features, well headers and well log information, an arbitrary symbol was chosen.
