Sonoma Valley Airport (FAA LID: 0Q3) is a public-use airstrip founded in 1946 by Wally Reichelt in Sonoma, California, United States. Its first California-certificated runway opened in August 1959. Located 4.14 nmi (7.67 km) south of central district of Sonoma (4.76 mi, 7.67 km) and 26.9 nmi (49.8 km) north of San Francisco (30.94 mi, 49.8 km), the airfield offers two asphalt runways, of which the 17/35 is restricted, needing prior permission to use. Open to public use for light aircraft, Sonoma Valley Airport does not allow ultralight and rotorcraft operations, except for MEDEVAC or law enforcement helicopters. There are no night operations. Flying hours begin at morning civil twilight and end at evening civil twilight. Fuel is self-serve. Among other fixed-wing aircraft, vintage planes can be seen on Sonoma Valley's apron, such as a fully restored, flying Curtiss P-40, a North American SNJ-4, three Boeing-Stearman PT-17 biplanes, a Globe Swift, a Cessna 195, a Douglas DC-3, a Dornier Do 27 or a Seabee amphibious. Others are being restored, like a Howard DGA-15. On the airfield are the Vintage Aircraft Company, air tour operator, and the North Bay Air Museum, a flying museum. Vintage Aircraft offers flights in restored WWII open cockpit Stearmans and AT6 Texan.

The 1898 Mare Island earthquake occurred in Northern California on March 30 at 23:43 local time with a moment magnitude of 5.8–6.4 and a maximum Mercalli intensity of VIII–IX (Severe–Violent). Its area of perceptibility included much of northern and central California and western Nevada. Damage amounted to $350,000 (about $10,700,000 inflation adjusted to 2018) and was most pronounced on Mare Island, a peninsula in northern San Francisco Bay. While relatively strong effects there were attributed to vulnerable buildings, moderate effects elsewhere in the San Francisco Bay Area consisted of damaged or partially collapsed structures, and there were media reports of a small tsunami and mostly mild aftershocks that followed. The mechanism of the shock is unknown, but several independent investigations focused on different aspects to gain a better understanding of the intensity, magnitude, source fault, and epicenter of this pre-instrumental event. Most investigators placed it under or to the north of San Pablo Bay, though two earthquake catalogs gave specific coordinates that place it within the confines of the San Pablo Bay National Wildlife Refuge. One of the numerous strike-slip faults of the San Andreas Fault System in the North Bay are most often named as the source fault, but one seismologist's paper detailed how an unnamed dip-slip fault may have been responsible. Several more recent studies gave alternate perspectives that named specific faults as the origin.

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.

Skaggs Island Naval Communication Station is a former United States Navy installation located near California State Route 37 between Novato and Vallejo, California. It was a secretive, secure, and self-contained naval base, engaged in a number of communications and intelligence gathering functions for the Navy and other federal intelligence organizations. The 3,310-acre (13.4 km2) site was purchased by the Navy in 1941, and closed in 1993. The antennas continued to be used for some time after that, but by 2013 they were removed along with all of the remaining buildings.

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).

Bliss, originally titled Bucolic Green Hills, is the default computer wallpaper of Microsoft's Windows XP operating system. It is a virtually unedited photograph of a green hill and blue sky with white clouds in the Los Carneros American Viticultural Area of California's Wine Country. Charles O'Rear took the photo in January 1996 and Microsoft bought the rights in 2000. It is estimated that billions of people have seen the picture, possibly making it the most viewed photograph in history.

Rancho Suscol was an 84,000-acre (340 km2) Mexican land grant in present day Sonoma County, California, Napa County, California, and Solano County, California, given in 1843 by Governor Manuel Micheltorena to General Mariano Guadalupe Vallejo. In a significant land law decision, the land claim was rejected by the US Supreme Court in 1862. Rancho Suscol extended from Rancho Petaluma on the west, south down to the San Francisco Bay and Mare Island and Carquinez Strait, and then to Rancho Suisun on the east. It included present day cities of Vallejo and Benicia.

Sonoma Skypark (FAA LID: 0Q9) is a public-use airport located three nautical miles (6 km) southeast of the central business district of Sonoma, a city in Sonoma County, California, United States.

Open to public use for light aircraft, the airfield offers various services, such as computer-based and in-flight training and self-serve 100LL aviation fuel. The hangars shelter many antique and classic aircraft, including a 1947 Luscombe 8E (Silvaire), a 1941 Interstate S-1A Cadet, a Briegleb BG 7 glider, and a 1946 Aeronca Champion. The airfield hosts a monthly Young Eagles Program, launched by the EAA in 1992 to give young people (from 8 to 17) an opportunity to fly in a general aviation airplane.

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.
