There are no actual geysers at The Geysers. The name is a misnomer that has stuck since the nineteenth century, when visitors mistook the roaring fumaroles and billowing steam vents of the Mayacamas Mountains for the erupting columns of water they had read about in Yellowstone. What this place actually offers is something rarer: a dry steam field, one of only a handful on Earth, where superheated vapor rises directly from rock heated by a magma chamber more than four miles beneath the surface. For 12,000 years, people have found uses for that steam. The Pomo, Wappo, and Lake Miwok peoples built steam baths and thermal pools here for healing, ceremony, and cooking. Today, 18 geothermal power plants draw from more than 350 wells across these ridges, producing roughly 20 percent of California's renewable energy. The Geysers is the world's largest developed geothermal field, and its story spans from indigenous medicine to industrial electricity -- with a presidential spa resort in between.

McLAUGHLIN and JULIE M. DONNELLY— NOLAN, Editors, Public domain. Long before European Americans arrived in the Mayacamas, six native tribes inhabited the area around The Geysers: three bands of Pomo people, two bands of Wappo people, and the Lake Miwok. They understood the thermal landscape intimately. The steam vents and hot pools served as n...

Godwin saw commercial potential in the same steam that had drawn indigenous peoples for thousands of years. He developed The Geysers Resort Hotel, a spa that traded on the area's otherworldly landscape of hissing vents and mineral-laden pools. ...

McLAUGHLIN and JULIE M. DONNELLY— NOLAN, Editors, Public domain. The geology beneath The Geysers reads like science fiction made real. Gravitational and seismic studies suggest that the heat source is a silicic magma chamber more than eight miles in diameter, sitting four miles underground. Steam rises through a greywacke sandstone reservoir, ...

McLAUGHLIN and JULIE M. DONNELLY— NOLAN, Editors, Public domain. Success brought its own problems. By 1999, decades of extraction had begun depleting the steam reservoir, and production dropped. The solution was inventive: treated wastewater, piped up to 50 miles from Lake County sanitation plants, is now injected into the geothermal field to ...

In September 2015, the Valley Fire damaged five of the field's facilities, causing severe harm to cooling towers while leaving the main powerhouses intact. Four years later, the Kincade Fire ignited at John Kincade Road and ...
