The Geysers turn mountain steam into power

The Geysers is one of those California names that needs a little explaining. The area is famous for geothermal steam, but the name stuck even though it is not a place with showy geysers like Yellowstone.

Long before power plants, Native people knew the thermal area. Later it became a strange tourist draw, with hot ground, mineral water, and a reputation that sounded half science and half tall tale.

The power story came later. The Geysers history traces early electricity work in the 1920s, including a small plant in 1923. In 1960, PG&E completed Unit 1, and federal energy history marks The Geysers as an early commercial-scale geothermal power development in California.

What makes the place interesting is the simple idea behind a complicated system. Heat deep underground makes steam. Wells bring that steam up. Power plants turn it into electricity. Then water management matters, because the steam field has to be cared for if it is going to keep working.

This is not a normal park stop, and most industrial areas should be treated as off limits unless a tour or visitor program is clearly open. Still, it gives the Lake-Sonoma county line a powerful story: California energy includes dams, oil fields, solar farms, wind, and mountain steam.
