Suisun Valley AVA
The Suisun Valley AVA is an American Viticultural Area in Solano County, California, located just east of the Napa Valley wine region in the Coast Range. It was established as a wine appellation on 27 December 1982, making it among the first AVAs of California (eighteenth overall), Napa Valley being the first. Geography Suisun Valley is a region in the California Coast Ranges that is bordered on the east side by the Blue Ridge of the Vaca Mountains, and on the west side by the Howell Mountains, which are also called the St. George Range. The valley is located almost entirely in Solano County with a northern terminus near the county line with Napa County, and a southern terminus at Suisun Bay in the estuary where the Sacramento River enters San Francisco Bay. Elevations on the valley floor range from above sea level, rising steeply to at Okell Hill on the north side, and to on the west side at Twin Sisters, a twin summit that is the high point of the Howell Mountains, as we ...

American Viticultural Area
An American Viticultural Area (AVA) is a designated wine grape-growing region in the United States, providing an official appellation for the mutual benefit of winery, wineries and consumers. Winemakers frequently want their consumers to know about the geographic pedigree of their wines, as wines from a particular area can possess distinctive characteristics. Consumers often seek out wines from specific AVAs, and certain wines of particular pedigrees can claim premium prices and loyal customers. If a wine is labeled with an AVA, at least 85% of the grapes that make up the wine must have been grown in the AVA, and the wine must be fully finished within the U.S. state, state where the AVA is located. Regulations The boundaries of AVAs are defined by the Tax and Trade Bureau (TTB), a component of the United States Department of the Treasury. The TTB defines AVAs at the request of wineries and other petitioners. Prior to the TTB's creation in 2003, the Treasury’s Bureau of Alcohol ...

Napa Valley AVA
Napa Valley is an American Viticultural Area (AVA) located in Napa County in California's Wine Country. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) on January 27, 1981. Napa Valley is considered one of the premier wine regions in the world. Records of commercial wine production in the region date back to the nineteenth century, but premium wine production dates back only to the 1960s. The combination of Mediterranean climate, geography and geology of the region are conducive to growing quality wine grapes. John Patchett established the Napa Valley's first commercial vineyard in 1858. In 1861 Charles Krug established another of Napa Valley's first commercial wineries in St. Helena. Viticulture in Napa suffered several setbacks in the late 19th and early 20th centuries, including an outbreak of the vine disease phylloxera, the institution of Prohibition, and the Great Depression. The wine industry in Napa Valley recovered, and helped by the results o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Pablo Bay
San Pablo Bay is a tidal estuary that forms the northern extension of San Francisco Bay in the East Bay and North Bay regions of the San Francisco Bay Area in northern California. Most of the Bay is shallow; however, there is a deep water channel approximately in the middle of the bay, which allows access to major ports in Sacramento, Stockton, Benicia, and Martinez; and other smaller ports on the Sacramento–San Joaquin River Delta. Geography San Pablo Bay was named after Rancho San Pablo, a Spanish land grant given to colonial Alta California settlers in 1815, on the bay at the site of the present-day city of San Pablo. The bay is approximately across and has an area of approximately . The bay receives the waters of the Sacramento and San Joaquin rivers, via Suisun Bay and the Carquinez Strait on its northeast end, and it connects to the Pacific Ocean via the San Francisco Bay on its southern end. The bay is heavily silted from the contributions of the two rivers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin Summit
A double summit, double peak, twin summit, or twin peak refers to a mountain or hill that has two summits, separated by a col or saddle. One well-known double summit is Austria’s highest mountain, the Großglockner, where the main summit of the Großglockner is separated from that of the Kleinglockner by the Glocknerscharte col in the area of a geological fault. Other double summits have resulted from geological folding. For example, on Mont Withrow in British Columbia, resistant sandstones form the limbs of the double summit, whilst the softer rock in the core of the fold was eroded.{{cite web , url=http://gsc.nrcan.gc.ca/natmap/cf/intro_e.php , title=Mt.

Twin Sisters (California)
thumbnail, 275px, Twin Sisters seen from the top of Mount Vaca. Twin Sisters are the twin summits of the highest peak in the Howell Mountains of Solano and Napa Counties, California. Description The peak straddles a ridge separating the Suisun Valley wine region in Solano County on the east side from the Napa Valley wine region on the west side, and is a prominent landmark visible from most points in Suisun Valley. The north summit at an elevation of is the tallest of the two, and the lower south summit rises to an elevation of . It is the second highest peak in Solano County, Mount Vaca being the highest. Origin of name The origin of the name Twin sisters is unknown. However, the name was evidently well established when Munro-Fraser (1879) wrote his ''History of Solano County''. B18A bomber crash site The lower (south) summit of Twin Sisters is the site of a pre World War II crash on 24 October 1941 of an Army Air Corps B-18A Bolo bomber that killed all five crew members ...

San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

Sacramento River
The Sacramento River ( es, Río Sacramento) is the principal river of Northern California in the United States and is the largest river in California. Rising in the Klamath Mountains, the river flows south for before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay. The river drains about in 19 California counties, mostly within the fertile agricultural region bounded by the California Coast Ranges, Coast Ranges and Sierra Nevada (U.S.), Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California. Historically, its watershed has reached as far north as south-central Oregon where the now, primarily, endorheic basin, endorheic (closed) Goose Lake (Oregon-California), Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento. The Sacramento and its wide natural floodplain were once abundant in fish and other aquatic creatures, notably one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...

Suisun Bay
Suisun Bay ( ; Wintun for "where the west wind blows") is a shallow tidal estuary (a northeastern extension of the San Francisco Bay) in Northern California. It lies at the confluence of the Sacramento River and San Joaquin River, forming the entrance to the Sacramento–San Joaquin River Delta, an inverted river delta. To the west, Suisun Bay is drained by the Carquinez Strait, which connects to San Pablo Bay, a northern extension of San Francisco Bay. Suisun Marsh, the tidal marsh land to the north, is the largest marsh in California. Grizzly Bay forms a northern extension of Suisun Bay. Suisun Bay is directly north of Contra Costa County. The bay was named in 1811, after the Suisunes, a Patwin tribe of Wintun Indians. The Central Pacific Railroad built a train ferry that operated between Benicia and Port Costa, California, from 1879 to 1930. The ferry boats ''Solano'' and ''Contra Costa'' were removed from service when the nearby Martinez railroad bridge was completed in ...

Howell Mountains
The Howell Mountains, which are also known as the Mt. George Range, are one of the California Coast Ranges. They divide the Suisun Valley on the east side, from Napa Valley on the west. Historically the southern part of the range has been referred to as both the Sierra de Suscol (Suscol Hills) and as the Sierra de Napa (Napa Hills). Geography The Howell Mountains begin at Sulphur Springs Mountain, near the towns of Vallejo and Benicia, and just north of the estuary where the Sacramento River flows into San Francisco Bay. The range then trends to the north and northwest for about to Howell Mountain, just northeast of St. Helena, California, where it merges with the Mayacamas Mountains. The Vaca Mountains, which are separated from the Howell Mountains by Suisun Valley on the east side, merge with the latter range northeast of St. Helena also. The crest of the range, which culminates at feet in the twin summit of Twin Sisters, represents the divide between the drainage of the Nap ...
