Bringing Boise’s Geothermal Past, Forward: “The Heat Beneath Your Feet” (SHRA)
In 1890 and 1891, the Boise Water Works Company pioneered the municipal-scale use of geothermal water when it completed two geothermal wells along the east Boise Front, which brought geothermally heated water to the surface.
