TheSonoma Mountains[2] are a northwest–southeast trendingmountain range of theInner Coast Ranges in theCalifornia Coast Ranges System, located inSonoma County, NorthernCalifornia.[3]
The Sonoma Mountains range is approximately fourteen miles (23 km) long. It separates theSonoma Creekwatershed from thePetaluma River andTolay Creek watersheds. The highest point of this range isSonoma Mountain, elevation 2,287 ft (697 m).[4]
Jack London State Historic Park,Crane Creek Regional Park, and theFairfield Osborn Preserve are all on Sonoma Mountain. A number ofthreatened andendangered species are found in the Sonoma Mountains including thefragrant fritillary (Fritillaria liliacea).
Many creeks rise in the Sonoma Mountains. From the northwestern slopes,Copeland Creek andHinebaugh Creek flow to theLaguna de Santa Rosa, eventually entering thePacific Ocean just south ofJenner, California.Matanzas Creek andSpring Creek flow north intoSanta Rosa Creek, another tributary of the Laguna.
Tributaries ofSonoma Creek rise on the eastern exposures of the Sonoma Mountains:Yulupa Creek,Carriger Creek,Graham Creek, Felder Creek, and Rogers Creek. These eventually enterSan Pablo Bay south ofSonoma, California.
The southwestern slopes drain toSan Pablo Bay by other routes: eitherTolay Creek or else some tributary of thePetaluma River such asLichau Creek,Lynch Creek, orAdobe Creek.
