The Geysers – Sonoma, CA

“The Geysers” – the world’s largest geothermal field spans an area of around 30 square miles and is found nestled deep in the Mayacamas Mountains of the Sonoma, Lake and Mendocino counties. Technically they are not geysers, but actually fumaroles (an opening in a planet’s crust, often in the neighborhood of volcanoes, which emits steam and gases such as carbon dioxide, sulfur dioxide, hydrogen chloride, and hydrogen sulfide).  Power from The Geysers provides electricity to Sonoma, Lake, Mendocino, Marin, and Napa counties. It is estimated that the development meets 60% of the power demand for the coastal region between the Golden Gate Bridge and the Oregon state line. Unlike most geothermal resources, the Geysers is a dry steam field, which mainly produces superheated steam.


For approximately 12,000 years, Native American tribes built steam baths at the Geysers and used the steam and hot water for healing purposes and cooking. Today, Velocurean can be found riding in the solitude of the idyllic landscape, steep climbs and long sweeping descents of those very same Mayacamas Mountains on Geysers Rd. We are also in search of those same healing powers. The roads are rugged and decrepit. The views are breathtaking and inspirational. It is everything that a cyclist desires. These are the conditions in which a Velocurean finds inner peace and healing.
