The Mayacamas Mountains currently support California mixed evergreen forest and California interior chaparral and woodlands habitats.
Naming According to Gudde:
The spelling Mayacamas is listed as an alternate name by the Board of Geographic Names.
Geothermal power Located in the Mayacamas mountain range is The Geysers, the world's largest and most developed geothermal field. It consists of more than 22 power plants scattered across an area of about 45 square miles (78 km2). The Geysers spans the Lake, Sonoma, and Mendocino counties in California, and provides energy to those counties. The electrical energy is generated when dry steam is pumped from geothermal reservoirs through turbines.
