The Cedars (IMAGE) American Geophysical Union Caption The Cedars, shown here, is a small, isolated set of springs flowing out of a large patch of red rock from Earth's mantle in Sonoma County, California. The Cedars is one of the few easily-accessible sites of serpentinization on land. Scientists report in a new study that they have found evidence of hardy, methane-producing microbes in water that surfaces from deep underground at The Cedars.
