Training Center Petaluma is a Coast Guard training facility in the northern California counties of Sonoma and Marin. Formerly the installation was the United States Army "Two Rock Station" . Approximately 4,000 military students train there each year. It is the only Coast Guard training center or large installation without a major operational component (air station, motor life boat station, etc) or waterfront. The training center is located in a rural area north of San Francisco at 38.25°N 122.79°W / 38.25; -122.79. It is about 9 mi (14 km) from the coast and 9 mi (14 km) west of the city of Petaluma, California, west of the junction of Tomales Road and Valley Ford Road, just south of Stemple Creek and the village of Two Rock, California. The facility occupies more than 800 acres (320 ha) of land, which include 129 family housing units and 90 other buildings. A small town, the training center also has a movie theater, RV and camping spots, over 10 miles of hiking and walking trails, barbershop and hair salon, tailor, chapel with regular services, bowling alley, and other amenities.

Two Rock is an unincorporated community in Sonoma County, California, United States. It is located on Stemple Creek in a rural area west of Petaluma. A hill named Dos Piedras (Spanish for "two rocks", 157 feet (48 m) above sea level) overlooks the community from the north. The community is named for the two rocks, between which the Mexican trail from San Rafael to Bodega passed. Two Rock had a post office located at the intersection of Bloomfield and Tomales Road, as well as a school 1.3 miles west of the former post office, on Tomales Road. A new school has since been built further east, but the original school building still stands. The main road is Valley Ford Road, which passes northwest–southeast through Two Rock. The Coast Guard's Training Center Petaluma is located just south of Two Rock. Two Rock used to provide basic services to local ranches, but little remains today.

The Petaluma Gap is a geographical region in Sonoma County, California which extends in a band from the Pacific Ocean to San Pablo Bay. It is an area of low land 22 to 31 miles (35 to 50 kilometers) wide in the coast ranges of the northern San Francisco Bay Area. The western edge of the gap is located in the coastal lowlands between Bodega Bay and Tomales Bay. The eastern edge of the gap is located at San Pablo Bay around the mouth of the Petaluma River. The city of Petaluma is near the center of the gap. The Petaluma Gap affects wind patterns (and thus microclimates and air quality) in the San Francisco Bay Area. Fresh marine air generally blows eastward through the gap, branching into southward and northward streams which blow toward the Carquinez Strait and Santa Rosa respectively. The southward stream brings marine air overland into the central Bay Area from the northwest. Warm air rises from the land and allows cold, moist air, plus winds and fog to move into the area.

Rancho Roblar de la Miseria was a 16,887-acre (68.34 km2) Mexican land grant in present-day Sonoma County, California given in 1845 by Governor Pío Pico to Juan Nepomuceno Padilla.

Petaluma Gap AVA is an American Viticultural Area established on January 8, 2018 by the U.S. Department of Treasury’s Alcohol and Tobacco Tax and Trade Bureau (TTB). The area spans 202,476 acres (316 sq mi) stretching through an 30 miles (48 km) inland valley from the Pacific coast at Bodega Bay southeast to Highway 37 at Sears Point on San Pablo Bay straddling the border of northern Marin and southern Sonoma counties. The AVA lies entirely within the North Coast AVA and partially in the Sonoma Coast AVA with eighty commercially-producing vineyards cultivating 4,000 acres (1,619 ha) and nine bonded wineries. The wind gap in its coastal mountain range funnels cooling breezes and fog east from the Pacific Ocean through the city of Petaluma to San Pablo Bay. A persistent afternoon breeze causes lower grape yields and longer hang time contributes to the AVA vintages' unique flavors and fruit characteristics which defines their character and distinction.
