Everything about Northern California totally explained
Northern California, sometimes referred to as
NorCal, is the northern portion of the
U.S. state of
California. The region contains the
San Francisco Bay Area, the state capital,
Sacramento; as well as the substantial natural beauty of the
redwood forests, the
northern California coast, the
Big Sur coastline area, the
Sierra Nevada including
Yosemite Valley and
Lake Tahoe,
Mt. Shasta which is the second-highest peak in the
Cascade Range, and the
Central Valley.
Native Americans arrived in Northern California perhaps as early as 5,000 to 8,000
BCE, and successive waves of arrivals led to one of the most densely populated areas of pre-Columbian North America. The arrival of European
explorers from the early
1500s to the mid-
1700s, didn't establish European settlements in Northern California. In 1770, the
Spanish mission at
Monterey was the first European settlement in the area, followed by other missions along the coast—eventually extending as far north as
Sonoma County.
Description
Definitions of what constitutes "Northern California" can vary. When the state is divided into two areas (Northern and Southern California) the term "Northern California" conventionally refers to the forty-eight counties north of the ten counties of
Southern California; the term is also occasionally applied to the area north of the
Tehachapi Mountains.
Because of California's large size and diverse geography, the state can be subdivided in other ways as well. For example, the Central Valley is a distinct region in itself both culturally and topographically from coastal California, though in Northern versus Southern California divisions, the Sacramento Valley and most of the San Joaquin Valley are usually placed in Northern California. Some residents of far Northern California define their region as encompassing only those areas to the north of the
San Francisco Bay Area and
Sacramento metropolitan areas.
Significance
Since the events of the
California Gold Rush, Northern California has long been a leader on the world's economic, scientific, and cultural stages. From the development of gold mining techniques in the nineteenth century which were later adopted around the world, to the development of world-famous on-line business models (
Google,
Yahoo!,
eBay), Northern California has been at the forefront of new ways of doing business. In science, advances range from being
the first to isolate and name fourteen
transuranic chemical
elements, to breakthroughs in microchip technology. Cultural contributions include
Ansel Adams,
beatniks, the
Summer of Love,
George Lucas,
Clint Eastwood, and the open, casual workplace first popularized in the Silicon Valley
dot-com boom and now widely in use around the world.
Geography and climate
Northern California's diverse geography ranges from the sandy beaches of the Pacific coast to the rugged, snow-capped
Sierra Nevada mountains in the east. The central portion of the region is dominated by the
Central Valley, one of the most vital agricultural areas in the country. The Sierra Nevada contains
Yosemite Valley, famous for its glacially-carved domes, and
Sequoia National Park, home to the largest living organisms on Earth, the
giant sequoia trees, and the highest point in the
contiguous United States,
Mount Whitney. The tallest living things on Earth, the ancient
redwood trees, dot the coastline, mainly north of San Francisco. Northern California is also home to the lowest and hottest place in North America,
Death Valley.
Bristlecone pines located in the
White Mountains are the oldest known trees in the world; one has an age of 4,700 years. The area is also known for its fertile farm and ranch lands,
wine country, the high mountains of the southern
Cascade Range, the
Trinity Alps, and the
Klamath Mountains, lakes, and the windswept sagebrush
steppe, in the northeast portion of the region.
The climate can be generally characterized by its
marine to warm
Mediterranean climates along the coast, to alpine climate zones in the high mountains. Apart from the
San Francisco Bay Area and
Sacramento metropolitan areas (and some other cities in the Central Valley), it's a region of relatively low population density.
History
Historical events to 1847
Inhabited for millennia by
Native Americans, from the
Shasta tribe in the north, to the
Miwoks in the central coast and Sierra Nevada, to the
Yokuts of the southern Central Valley, Northern California was among the most densely populated areas of pre-Columbian North America.
European explorers
The first European to explore the coast was Juan Rodríguez Cabrillo, sailing for the Spanish Crown; in 1542, Cabrillo's expedition sailed perhaps as far north as the
Rogue River in today's
Oregon. Beginning in 1565, the Spanish
Manila Galleons crossed the Pacific Ocean from
Mexico to the Spanish
Philippines, with silver and gemstones from Mexico. The Manila Galleons returned across the northern Pacific, and reached North America usually off the coast of Northern California, and then continued south with their Asian trade goods to Mexico.
In 1579, Northern California was visited by the English explorer
Sir Francis Drake who landed north of today's
San Francisco and claimed the area for
England. In 1602, the Spaniard
Sebastián Vizcaíno explored California's coast as far north as
Monterey Bay, where he went ashore. Other Spanish explorers sailed along the coast of Northern California for the next 150 years, but no settlements were established.
Spanish era
The first European inhabitants were Spanish missionaries, who built
missions along the California coast. The mission at
Monterey was first established in 1770, and at
San Francisco in 1776. In all, some 15 missions stretched along the coast from
Sonoma to
Santa Barbara (and still more missions to the southern tip of
Baja California). In 1786, the
French signaled their interest in the Northern California area by sending a voyage of exploration to Monterey.
The first twenty years of the
19th century continued the colonization of the Northern California coast by Spain. By 1820, Spanish influence extended inland approximately 25 to from the missions. Outside of this zone, perhaps 200,000 to 250,000 Native Americans continued to lead traditional lives. The
Adams-Onís Treaty, signed in 1819 between Spain and the young
United States, set the northern boundary of the Spanish claims at the 42nd parallel, effectively creating today's northern boundary of Northern California.
Russian presence
Russians, from
Alaska, were moving down the coast, and in 1812 established
Fort Ross, a fur trading outpost on the coast of today's
Sonoma County. Fort Ross was the southernmost point of expansion, meeting the Spanish northern expansion some north of San Francisco. In 1841, as the American presence in Northern California began to increase and politics began to change the region, a deal was made with John Sutter and the Russians abandoned their Northern California settlements.
Mexican era
After Mexico gained
independence from Spain in 1821, Mexico continued Spain's missions and settlements in Northern California as well as Spain's territorial claims. The Mexican
Californios (Spanish-speaking Californians) in these settlements primarily traded cattle hides and
tallow with American and European merchant vessels.
In 1825, the
Hudson's Bay Company established a major trading post
just north of today's
Portland, Oregon. British fur trappers and hunters then used the
Siskiyou Trail to travel throughout Northern California. The leader of a further French scientific expedition to Northern California,
Eugene Duflot de Mofras, wrote in 1840 "
...it is evident that California will belong to whatever nation chooses to send there a man-of-war and two hundred men." By the 1830s, a significant number of non-
Californios had immigrated to Northern California. Chief among these was
John Sutter, a European immigrant from
Switzerland, who was granted 48,827
acres (19,759
ha)
centered on the area of today's
Sacramento.
American interest
American trappers began entering Northern California in the 1830s. In 1834, American visionary
Ewing Young led a herd of horses and mules over the
Siskiyou Trail from missions in Northern California to British and American settlements in
Oregon. Although a small number of American traders and trappers had lived in Northern California since the early 1830s, the first organized overland party of American immigrants to arrive in Northern California was the Bidwell-Bartleson party of 1841 via the new
California Trail. Also in 1841, an overland exploratory party of the
United States Exploring Expedition came down the
Siskiyou Trail from the Pacific Northwest. In 1846, the
Donner Party earned notoriety as they struggled to enter Northern California.
Beginning of United States era
When the
Mexican-American War was declared on May 13, 1846, it took almost two months (mid-July 1846) for word to get to California. On June 15, 1846, some 30 non-Mexican settlers, mostly Americans, staged a revolt and seized the small Mexican garrison in Sonoma. They raised the "
Bear Flag" of the
California Republic over Sonoma. It lasted one week until the U.S. Army, led by
John Frémont, took over on June 23. The California state flag today is based on this original Bear Flag, and continues to contain the words "California Republic."
Commodore
John Drake Sloat ordered his naval forces to occupy
Yerba Buena (present
San Francisco) on July 7 and within days American forces controlled San Francisco, Sonoma, and Sutter's Fort in Sacramento. News of the discovery soon spread, resulting in some 300,000 people coming to California from the rest of the United States and abroad.
San Francisco grew from a tiny hamlet of tents to a
boomtown, and roads, churches, schools and other towns were built. New methods of transportation developed as
steamships came into regular service and
railroads were built. However, the Gold Rush also had negative effects:
Native Americans were attacked and pushed off traditional lands, and
gold mining caused environmental harm.
Population and agricultural expansion (1855-1899)
The decades following the Gold Rush brought dramatic expansion to Northern California, both in population and economically - particularly in agriculture. The completion of the
First Transcontinental Railroad in 1869, with its terminus in Sacramento, meant that Northern California's agricultural produce (and some manufactured goods) could now be shipped economically to the rest of the United States. In return, immigrants from the rest of the United States (and Europe) could comfortably come to Northern California. A network of railroads spread throughout Northern California, and in 1887, a
rail link was completed to the
Pacific Northwest. Almost all of these railways came under the control of the
Southern Pacific Railroad, headquartered in San Francisco, and San Francisco continued as a financial and cultural center.
Substantial tensions during this era included nativist sentiments (primarily against Chinese immigrants), tensions between the increasing power of the Southern Pacific Railroad and small farmers, and the beginnings of the labor union movement.
Population
The population of the forty-eight counties of Northern California has shown a steady increase over the years. The 1850 census almost certainly undercounted the population of the area, especially undercounting a still substantial Native American population.
The largest percentage increase outside the Gold Rush era (51%) came in the decade of the 1940s, as the area was the destination of many post-War veterans and their families, attracted by the greatly-expanding industrial base and (often) by their time stationed in Northern California during World War II. The largest absolute increase occurred during the decade of 1980s (over 2.1 million person increase), attracted in part by the expansion taking place in
Silicon Valley.
Cities
Northern California's largest
metropolitan area is the
San Francisco Bay Area which includes the cities of
San Francisco,
San Jose,
Oakland, and their many
suburbs, as well as the
Silicon Valley high-tech region.
In recent years the Bay Area has drawn more commuters from as far as
Central Valley cities like the California state capital,
Sacramento, from
Stockton south of Sacramento, and
Modesto about 30 miles to the south. With expanding development in all these areas, the San Francisco Bay Area, Monterey Bay Area, and central part of the Central Valley and Sierra Nevada foothills may now be viewed as part of a single
megalopolis.
The state's largest inland city,
Fresno, is farther south in the Central Valley, but considered part of Northern California in cases when the state is divided into two parts. Other cities in the region include
Redding at the northern end of the Central Valley,
Chico, in the mid-north of the Valley, and
Eureka on the northern coast.
