Mount Hood, also known as Hood Mountain is a mountain near the southeastern edge of Santa Rosa, California at the northeast of the Sonoma Valley and attains a height of 2,733 feet (833 m). The original name was Mount Wilikos, an Indian name meaning "willows." Most of the drainage from Mount Hood contributes to the headwaters of Sonoma Creek. A prominent feature is the extensive rock face visible on the upper half of the mountain as viewed from State Route 12. The habitats on the mountain include mixed oak forest, pygmy forest, chaparral and riparian zones. In prehistoric times the slopes of Mount Hood were inhabited by a division of the Yuki tribe. Most of Mount Hood is within the Hood Mountain Regional Park maintained by Sonoma County. Mount Hood is part of the inner coast Mayacamas Range, and lies mostly within Sonoma County, with a part of the mountain geographically within Napa County. Mount Hood affords overlooks of the Pacific Ocean, San Francisco Bay and "a spectacular view east to the Sierra Nevada Range."
Sonoma Mountain is a prominent landform within the Sonoma Mountains of southern Sonoma County, California. At an elevation of 2,463 ft (751 m), Sonoma Mountain offers expansive views of the Pacific Ocean to the west and the Sonoma Valley to the east. In fact, the viticultural area extends in isolated patches up the eastern slopes of Sonoma Mountain to almost 1,700 feet (520 m) in elevation.
Matanzas Creek is an 11.4-mile-long (18.3 km) year-round stream in Sonoma County, California, United States, a tributary of Santa Rosa Creek.
Santa Rosa Creek is a 22-mile-long (35 km) stream in Sonoma County, California, which rises on Hood Mountain and discharges to the Laguna de Santa Rosa by way of the Santa Rosa Flood Control Channel. This article covers both the creek and the channel.
The Fairfield Osborn Preserve is a 450-acre nature reserve situated on the northwest flank of Sonoma Mountain in Sonoma County, California. There are eight plant communities within the property, oak woodland being the dominant type. Other communities include chaparral, Douglas fir woodland, native Bunch grass, freshwater marsh, vernal pool, pond and riparian woodland. The flora is extremely diverse including many native trees, shrubs, wildflowers, grasses, lichens and mosses. A diverse fauna inhabits this area including black-tailed deer, coyote, bobcat and an occasional mountain lion; moreover, there are abundant avifauna, amphibians, reptiles and insects.
Copeland Creek is a 9.0-mile-long (14.5 km) perennial stream that rises on Sonoma Mountain in Sonoma County, California.
The Laguna de Santa Rosa is a 22-mile-long (35 km) wetland complex that drains a 254-square-mile (660 km2) watershed encompassing most of the Santa Rosa Plain in Sonoma County, California, United States.
Spring Creek, in Sonoma County, California, is a 6.0-mile-long (9.7 km) stream that rises in the northern part of the Sonoma Mountains within Annadel State Park, draining the western slopes of Bennett Mountain and feeding into Matanzas Creek at Doyle Community Park below the Matanzas Creek Reservoir.
Yulupa Creek is a 2.8-mile-long (4.5 km) southeast-flowing perennial stream that rises on the southeastern flanks of the northern Sonoma Mountains in Sonoma County, California, United States. This creek, which drains the eastern slopes of Bennett Mountain, is tributary to Sonoma Creek, which in turn discharges to San Pablo Bay. Yulupa Avenue in Santa Rosa is presumably named after this creek.
Graham Creek is a 2.9-mile-long (4.7 km) perennial stream in Sonoma County, California, tributary to Sonoma Creek. Graham Creek rises in the northern Sonoma Mountains and flows generally northeasterly down the northeastern flank of Sonoma Mountain. Historically this watercourse was called Wild Water Creek, a name used in the time of author Jack London, some of whose work was inspired by the stream. Steelhead, Oncorhynchus mykiss, have historically entered Graham Creek via Sonoma Creek for spawning. Stream surveys conducted from 1966 to 1986 indicated significant, but declining populations of anadromous fish. The spawning habitat of Graham Creek is considered medium to high value, with both winter and summer sheltering characteristics.
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".
Washoe Creek is a perennial stream located in Sonoma County, California. It is about 2 mi (3 km) long and discharges to the Laguna de Santa Rosa.
Bennett Valley is a northwest- to southeast-trending valley in Sonoma County, California, US, approximately 1 mile (1.6 km) wide in its northwestern portion, where the southeast extremity of Santa Rosa, California is located. The axis of the valley floor slopes 40 feet (12 m) per mile from the pinched central portion of the valley, where knolls divide the northwestern from the southeastern segment of the valley. Bennett Valley is drained by Matanzas Creek which is incised into the valley floor; an unnamed stream and Spring Creek drain into Matanzas Creek from the east side of Bennett Valley below the Matanzas Creek Reservoir. A flood-control reservoir on Matanzas Creek in the central portion of the valley collects water from the drainage of the upper portion of the valley. Precipitation in the valley varies from approximately 35 to 40 inches per year. The latter amount falls on Taylor Mountain, located immediately above Bennett Valley, in an outlier spur of the Sonoma Mountains sometimes called the Los Gullicos Range. Rainfall occurs primarily during winters, separated by warm dry summers. Bennett Valley is accessed chiefly via Bennett Valley Road, which traverses the valley floor to connect southeast Santa Rosa with Warm Springs Road in Glen Ellen.
Piner Creek is a stream in northeast Santa Rosa, California, United States which originates as an outlet of Fountaingrove Lake. Piner Creek discharges to Santa Rosa Creek which in turn joins the Laguna de Santa Rosa. The upper reaches in the foothills of the Mayacamas Mountains are at elevations of 200 to 300 feet, while the lower and middle reaches are located on the Santa Rosa Plain at elevations of between the 110- and 140-foot contours; therefore, these lower reaches have a gradient of about 1:250 toward the southwest. Geologic studies in the lower and middle reaches of Piner Creek indicate groundwater levels ranging from three to 15 feet below the surface. Prior to extensive urban development of the middle and lower reaches, the landscape earlier bore extensive agricultural uses including plum orchards, which fruit was subsequently processed for prunes.
Calabazas Creek is a 5.5-mile-long (8.9 km) stream in the Sonoma Valley, California, United States, that rises in the southern Mayacamas Mountains and empties into Sonoma Creek near Glen Ellen.
Crane Creek is a stream in Sonoma County, California, United States which rises in the northern Sonoma Mountains. This watercourse flows through Crane Canyon and the Crane Creek Regional Park situated on the northwestern flank of Sonoma Mountain. Crane Creek forms a confluence with Hinebaugh Creek in the city of Rohnert Park; thereafter, the channelized Hinebaugh Creek flows westerly to discharge to the Laguna de Santa Rosa. Hiking access to the upper Crane Creek reaches is from Roberts Road off Petaluma Hill Road.
The Galbreath Wildlands Preserve is a 3,670-acre (14.9 km2) nature reserve in Mendocino County, California, United States, established in 2004 in honor of Fred Burckhalter Galbreath (1901-2000). The preserve, a former sheep ranch, is located in the Outer Coast Range 17 miles (27 km) from the coast, near Yorkville. The Preserve features woodland, forest and grassland communities that lie at the edge of coastal fog influence. Lands are in the upper Rancheria sub-basin of the Navarro Watershed and contain 1st - 5th order streams. The Preserve's forests are primarily second-growth coniferous forest and hardwood.
Alamitos Creek or Los Alamitos Creek is a 7.7-mile-long (12.4 km) creek in San Jose, California, which becomes the Guadalupe River when it exits Lake Almaden and joins Guadalupe Creek. Los Alamitos Creek is located in Almaden Valley and originates from the Los Capitancillos Ridge in the Santa Cruz Mountains, near New Almaden. This creek flows through the Valley's Guadalupe Watershed, which is owned by the Santa Clara Valley Water District. The creek flows in a generally northwesterly direction after rounding the Los Capitancillos Ridge and the town of New Almaden, in the southwest corner, before ambling along the Santa Teresa Hills on northeast side of the Almaden Valley. Its environment has some relatively undisturbed areas and considerable lengths of suburban residential character. Originally called Arroyo de los Alamitos, the creek's name is derived from "little poplar", "alamo" being the Spanish word for "poplar" or "cottonwood".
