Arroyo Seco is a 6.9-mile-long (11.1 km) tributary stream to Schell Creek in southern Sonoma County, California, United States. In Spanish arroyo seco means "dry creek". Arroyo Seco Creek drains a portion of the western slopes of the southern Mayacamas Mountains. Its 11.4-square-mile (30 km2) watershed, along with the entire Mayacamas mountain block, was formed in the Miocene era by volcanic action and with tectonic uplift about 12 million years ago. Soils of the immediate streambed and its vicinity are classified as the riverwash series, recent deposition of sands and gravels.Arroyo Seco Creek springs near the Napa County line about 4 mi (6 km) northeast of Sonoma, California. It flows southward, emerging from near Sonoma Valley Hospital. After a confluence with Haraszthy Creek, it crosses under State Route 12 near Schellville, California, where it flows into Schell Creek. Schell Creek discharges to a network of sloughs that eventually empty into Sonoma Creek, which in turn empties into the Napa Sonoma Marsh and San Pablo Bay.

Schellville is an unincorporated community in Sonoma County, California, United States. Schellville was named after Theodore L. Schell, who lived on a ranch nearby. The community is located in the vicinity of the junction of California State Route 12 and California State Route 121 south of Sonoma, and had a post office from 1888 to 1931. Schellville also boasted a newspaper called the Schellville Ray, which was also used to promote local plots of land for sale.Schellville has been a regionally important rail junction since completion of the Santa Rosa and Carquinez Railroad to Napa Junction in 1888. The 2 mile long Northwestern Pacific Railroad railyard is located just south of the Schellville Depot at California State Routes 12/121 and Eighth Street East. Service along the mainline was planned to start again in July 2010, from the California Northern interchange at Schellville, north to Windsor until delays pushed the start date to 2011. The depot building, which was formerly a train station, now houses railroad equipment. Until it ended in 2014, Valley of the Moon Commute Club operated a once-daily transbay express service to San Francisco via Schellville, Sonoma, El Verano, Boyes Hot Springs, Santa Rosa, and San Rafael. Due to its low position along Sonoma Creek, the town regularly experiences flooding in high-rain years (about every 5–10 years).

The California Republic (Spanish: La República de California), or Bear Flag Republic, was an unrecognized breakaway state from Mexico, that for 25 days in 1846 militarily controlled an area north of San Francisco, in and around what is now Sonoma County in California.In June 1846, thirty-three American immigrants in Alta California who had entered without official permission rebelled against the Mexican department's government. Among their grievances were that they had not been allowed to buy or rent land and had been threatened with expulsion. Mexican officials had been concerned about a coming war with the United States and the growing influx of Americans into California. The rebellion was covertly encouraged by U.S. Army Brevet Captain John C. Frémont, and added to the troubles of the recent outbreak of the Mexican–American War. The name "California Republic" appeared only on the flag the insurgents raised in Sonoma. It indicated their aspiration of forming a republican government under their control. The rebels elected military officers but no civil structure was ever established. Their flag, featuring a silhouette of a California grizzly bear, became known as the Bear Flag and was later the basis for the official state flag of California. Three weeks later, on July 5, 1846, the Republic's military of 100 to 200 men was subsumed into the California Battalion commanded by Brevet Captain John C. Frémont. The Bear Flag Revolt and whatever remained of the "California Republic" ceased to exist on July 9 when U.S. Navy Lieutenant Joseph Revere raised the United States flag in front of the Sonoma Barracks and sent a second flag to be raised at Sutter's Fort.

Los Carneros AVA (also known as Carneros AVA) is an American Viticultural Area which includes parts of both Sonoma and Napa counties in California, U.S.A. It is located north of San Pablo Bay. The proximity to the cool fog and breezes from the bay makes the climate in Los Carneros cooler and more moderate than the wine regions farther north in Napa Valley and Sonoma Valley. The cooler climate has made Los Carneros attractive for the cultivation of cooler climate varietals like Pinot noir and Chardonnay. Many of the grapes grown in Los Carneros are used for sparkling wine production. Receiving its AVA status in 1983, the Carneros area was the first wine region in California to be defined by its climate characteristics rather than political boundaries.
