Although modified by piping into the Hot Sulphur Springs resort, there appeared to be about 5 to 10 springs having water temperatures of 104-111 degrees F (40-44 degrees C). The springs issue from a large travertine mound and a marshy area. The combined total discharge was 50 gpm and the waters were a sodium bicarbonate type with elevated sulfate. Water quality data from the hot springs is included in the report appendix. Also included in this report is an evaluation of soil mercury as a geothermal exploration tool used to delineate faults or permeable zones.
