Sonoma Valley is a valley located in southeastern Sonoma County, California, in the North Bay region of the San Francisco Bay Area. Known as the birthplace of the California wine industry, [1] [2] the valley is home to some of the earliest vineyards and wineries in the state, some of which survived the phylloxera epidemic of the 1870s and the impact of prohibition in the early 20th century. Today, the valley's wines are promoted by the U.S. federal government's Sonoma Valley and Carneros AVAs (or American Viticultural Areas).
Sonoma Valley offers a wide range of year-round festivals and events, including the Sonoma International Film Festival. Points of interest include the Quarryhill Botanic Garden, Mission San Francisco Solano, Jack London State Historic Park, Sonoma State Historic Park and the Blue Wing Inn of 1840.
The valley is located in southeastern Sonoma County between the Mayacamas Mountains and Sonoma Mountains. It stretches from San Pablo Bay in the south to the city of Santa Rosa in the north. Sonoma Creek flows down the valley to the bay. The area includes the incorporated city of Sonoma and part of the city of Santa Rosa, as well as numerous unincorporated communities, including Kenwood and Glen Ellen near Santa Rosa and, near Sonoma, El Verano, Boyes Hot Springs, Fetters Hot Springs, and Agua Caliente.
Once a valley of the coastal Miwok, Pomo and Wintun peoples, called the "Valley of the Moon" in their legends, the valley was selected by the Franciscan order of Spain as the site to build the Mission San Francisco Solano, the northernmost mission in their chain of twenty-one missions built in Alta California. [3] Established in 1823 and named to honor St. Francis Solanus, Mission Solano was the sole California mission established under the rule of a newly independent Mexico. Within two generations of the Spaniards' arrival, however, the indigenous societies of the region were dispossessed of their land and decimated by diseases to which Europeans were resistant. Soon after the Sonoma mission was built, it was secularized by the Mexican government, and, under the orders of Lieutenant, later General Mariano Guadalupe Vallejo, el Pueblo de Sonoma (the town of Sonoma) was laid out in the standard form of a Mexican town, centered around the historic plaza, which is still the town's focal point. [3] Also known as "Valley of the Seven Moons" [4] The raising of the first California Bear Flag and Vallejo's arrest in 1846 by a band of Americans claiming to act on the orders of Col. John C. Fremont was the initial act that founded the Bear Flag Republic. [5] Vallejo later transferred his allegiance with US statehood (1850), and with his amassed land holdings guided the development of the town and dispensed large ranches throughout the valley. [6] California's first wineries were established here, including Buena Vista Winery (1857) and Gundlach Bundschu (1858).
The other communities in the valley, such as Kenwood, Glen Ellen, Schellville, and Boyes Hot Springs, were founded later in the 19th century, some as resorts centered on the geothermic hot springs that still well up from deep within the earth. Boyes Hot Springs and Agua Caliente were popular health retreats for tourists from San Francisco and points beyond until the middle of the 20th century. Today the Sonoma Mission Inn in Boyes Hot Springs remains as a main destination resort, and the wineries, the historic sites, and the area's natural beauty are the main tourist attractions.
In October 2017, Sonoma Valley was badly affected by the Tubbs Fire.
The phrase "Valley of the Moon" was first recorded in an 1850 report by General Mariano Guadalupe Vallejo to the California Legislature. [7]
According to Jack London, who had a ranch there, the Native American word Sonoma means "valley of the moon". He used it for his book of the same name. But there are several other possible translations for Sonoma (see Sonoma County, California). According to the Miwok tribes that lived in the valley, and the Pomo, it meant "valley of the moon" or "many moons". Settlers may have accidentally translated the words "many moons" into "valley of moons". Miwok legends say that the moon seemingly rose from this valley, or was "nestled" in the valley, or may have even sprung up multiple times in one night. [8]
In the native languages there is also a constantly recurring ending tso-noma, from tso, the earth; and noma, village; hence tsonoma, "earth village". [9] Other sources say Sonoma comes from the Patwin tribes west of the Sacramento River, and their Wintu word for "nose". Per California Place Names, "the name is doubtless derived from a Patwin word for 'nose', which Padre Arroyo (Vocabularies, p. 22) gives as sonom (Suisun)." Spaniards may have found an Indian chief with a prominent protuberance and applied the nickname of Chief Nose to the village and the territory. [10] The name may have applied originally to a nose-shaped geographic feature. [11]
The Sonoma Valley is part of the Coast Range Physiographic province. Basement rocks that make up the valley at great depth are the Great Valley Sequence shale, sandstone and conglomerate deposited in a continental slope- to abyssal plain environment via turbidite flows. The Cretaceous Great Valley Sequence overlies and contacts the Franciscan Complex along the Coast Range Thrust. The Jurassic-Cretaceous Franciscan Complex includes crumpled, uplifted terranes that have resulted from the subduction of the former oceanic Farallon Plate under the North American continent. During late Miocene-Pliocene time (~10 to ~4 million years) the area was attended by volcanism (Late Miocene Tolay Volcanics and Late Miocene - Pliocene Sonoma Volcanics) which are interbedded with the late Miocene-Pliocene Petaluma Formation. The (~9 to 4 million year old) Petaluma Formation was a fresh-water river system flowing from east to west and through the volcanics.
At that time, volcanic lava flows and river sands and gravels were actively deposited together, hence "interbedded lavas and gravels". The volcanoes may have been similar to island arcs. The Petaluma Formation is found in outcrop from Sears Point to Santa Rosa (through Sonoma Mountain) and as far west as Cotati where it interfingers with a marine sandstone called the Wilson Grove Formation. Gravels in the Petaluma Formation did not come from rocks located in Napa, but have been sourced to mountains east of San Jose, California. This does not mean rivers flowed northward from San Jose to Sonoma; rather, strike-slip movement along the Hayward-Sonoma Valley-Carneros fault system has dislocated present-day Sonoma County north and away from the mountains in San Jose where the basin formed.
The valley is drained by Sonoma Creek, whose headwaters rise in Sugarloaf Ridge State Park and discharge into the San Pablo Bay at the Napa Sonoma Marsh. Some of the principal tributaries to Sonoma Creek are Yulupa Creek, Graham Creek, Calabazas Creek, Bear Creek, Schell Creek and Carriger Creek.
In spring 2006, the United States Geological Survey in conjunction with the Sonoma County Water Agency completed a comprehensive basin-wide groundwater study to characterize groundwater resources in the Sonoma Valley. The report can be obtained on the USGS publications website. Currently, a Basin Advisory Panel, composed of stakeholders from agriculture, environmental groups, domestic well owners, municipalities and government is working to develop a groundwater management plan to protect groundwater resources in the valley.
Mission San Francisco Solano was the 21st, last, and northernmost mission in Alta California. It was named for Saint Francis Solanus. It was the only mission built in Alta California after Mexico gained independence from Spain. The difficulty of its beginning demonstrates the confusion resulting from that change in governance. The California Governor wanted a robust Mexican presence north of the San Francisco Bay to keep the Russians who had established Fort Ross on the Pacific coast from moving further inland. A young Franciscan friar from Mission San Francisco de Asis wanted to move to a location with a better climate and access to a larger number of potential converts.

Don Mariano Guadalupe Vallejo was a Californio general, statesman, and public figure. He was born a subject of Spain, performed his military duties as an officer of the Republic of Mexico, and shaped the transition of Alta California from a territory of Mexico to the U.S. state of California. He served in the first session of the California State Senate. The city of Vallejo, California, is named after him, and the nearby city of Benicia is named after his wife.
Wine Country is the region of California, in the northern San Francisco Bay Area, known worldwide as a premier wine-growing region. The region is famed for its wineries, its cuisine, Michelin star restaurants, boutique hotels, luxury resorts, historic architecture, and culture. Viticulture and wine-making have been practiced in the region since the Spanish missionaries from Mission San Francisco Solano established the first vineyards in 1812.
The Coast Miwok are an Indigenous people of California that were the second-largest tribe of the Miwok people. Coast Miwok inhabited the general area of modern Marin County and southern Sonoma County in Northern California, from the Golden Gate north to Duncans Point and eastward to Sonoma Creek. Coast Miwok included the Bodega Bay Miwok, or Olamentko (Olamentke), from authenticated Miwok villages around Bodega Bay, the Marin Miwok, or Hookooeko (Huukuiko), and Southern Sonoma Miwok, or Lekahtewutko (Lekatuit). While they did not have an overarching name for themselves, the Coast Miwok word for people, Micha-ko, was suggested by A. L. Kroeber as a possible endonym, keeping with a common practice among tribal groups and the ethnographers studying them in the early 20th Century and with the term Miwok itself, which is the Central Sierra Miwok word for people.
The North Bay is a subregion of the San Francisco Bay Area, in California, United States. The largest city is Santa Rosa, which is the fifth-largest city in the Bay Area. It is the location of the Napa and Sonoma wine regions, and is the least populous and least urbanized part of the Bay Area. It consists of Marin, Napa, Solano and Sonoma counties.
The Suisunes were a Patwin tribe of Wintun people, originating in the Suisun Bay and Suisun Marsh regions of Solano County in Northern California. Their traditional homelands stretched between what is now Suisun City, Vacaville and Putah Creek around 200 years ago. The Suisunes' main village, Yulyul, is believed to be where Rockville, California is located today. Father Abella, visitor to the tribe in 1811, indicated they resided in the present location of Fairfield, north of the Suisun Bay. One of the Suisunes' primary food sources was acorns. Their diet also included fish as well as miner's lettuce. Their huts were conical wikiups made of rushes or tule thatch.
Sonoma Creek is a 33.4-mile-long (53.8 km) stream in northern California. It is one of two principal drainages of southern Sonoma County, California, with headwaters rising in the rugged hills of Sugarloaf Ridge State Park and discharging to San Pablo Bay, the northern arm of San Francisco Bay. The watershed drained by Sonoma Creek is roughly equivalent to the wine region of Sonoma Valley, an area of about 170 square miles (440 km2). The State of California has designated the Sonoma Creek watershed as a “Critical Coastal Water Resource”. To the east of this generally rectangular watershed is the Napa River watershed, and to the west are the Petaluma River and Tolay Creek watersheds.
Rancho Petaluma Adobe is a historic ranch house in Sonoma County, California. It was built from adobe bricks in 1836 by order of Mariano Guadalupe Vallejo. It was the largest privately owned adobe structure built in California and is the largest example of the Monterey Colonial style of architecture in the United States. A section of the former ranch has been preserved by the Petaluma Adobe State Historic Park and it is both a California Historic Landmark and a National Historic Landmark. The Rancho Petaluma Adobe State Historic Park is located on Adobe Road on the east side of the present-day town of Petaluma, California.
Tolay Creek is a 12.5-mile-long (20.1 km) southward-flowing stream in southern Sonoma County, California, United States, which flows through Tolay Lake and ends in north San Pablo Bay.
Sonoma State Historic Park is a California State Park located in the center of Sonoma, California. The park consists of six sites: the Mission San Francisco Solano, the Sonoma Barracks, the Blue Wing Inn, La Casa Grande, Lachryma Montis, and the Toscano Hotel.
Sonoma County wine is wine made in Sonoma County, California, in the United States.
Rancho Petaluma was a 66,622-acre (269.61 km2) Mexican land grant in present-day Sonoma County, California given in 1834 by Governor José Figueroa to Mariano Guadalupe Vallejo. Rancho Petaluma stretched from Petaluma River on the west over the hills and down to Sonoma Creek on the east, including all land that lay between these two waterways from the edge of San Francisco Bay to approximately the present site of Glen Ellen. The rancho included present-day Petaluma and Lakeville.
Cline Cellars Winery is a family owned and operated winery located in the Carneros wine appellation of Sonoma County, California that specializes in Zinfandels, Rhône-style wines, Chardonnay and Pinot Noir.
The Sonoma Volcanics are a geologic formation of volcanic origin that is widespread in Napa and Sonoma counties, California. Most of the formation is Pliocene in age and includes obsidian, perlitic glass, diatomaceous mud, pyroclastic tuff, pumice, rhyolite tuffs, andesite breccias and interbedded volcanic (basalt) lava flows. The formation serves as the parent material for many of the soils in the Napa and Sonoma wine regions.
The Sonoma Barracks is a two-story, wide-balconied, adobe building facing the central plaza of the City of Sonoma, California. It was built by order of Mariano Guadalupe Vallejo to house the Mexican soldiers that had been transferred from the Presidio of San Francisco in 1835. The Presidio Company and their commander, Vallejo, were also responsible for controlling the Native Americans living on the northern border of Mexican California.
The 2014 South Napa earthquake occurred in the North San Francisco Bay Area on August 24 at 03:20:44 Pacific Daylight Time. At 6.0 on the moment magnitude scale and with a maximum Mercalli intensity of VIII (Severe), the event was the largest in the San Francisco Bay Area since the 1989 Loma Prieta earthquake. The epicenter of the earthquake was located to the south of Napa and to the northwest of American Canyon on the West Napa Fault.
Moon Mountain District Sonoma County is an American Viticultural Area (AVA) within Sonoma Valley and North Coast viticultural areas, just north of the city of Sonoma. This mountainous region on the very eastern edge of Sonoma County has a historic reputation for producing rich, intensely-flavored wines from Cabernet Sauvignon and Syrah varietals since the 1880s. The District was established on November 1, 2013, by the Alcohol and Tobacco Tax and Trade Bureau (TTB). Its designation covers 17,663 acres (28 sq mi) of land stretching north-south along the western slopes of the Mayacamas mountains between Sugarloaf Ridge State Park and Los Carneros viticultural area with the Napa Valley’s Mount Veeder viticultural area outlining the eastern slopes. Its name is derived from Moon Mountain Road, which traverses through the area and itself a reference to Sonoma, which means 'valley of the moon' in the local Native American dialect. A clear view to San Francisco 50 miles (80 km) south is not uncommon from Moon Mountain District vineyards.
