in the north to Cabo San Lucas, Baja California
Baja California
Sur in the south. It ranges from 40 km (25 miles) at its narrowest to 320 km (200 miles) at its widest point and has approximately 3,000 km (1,900 miles) of coastline and approximately 65 islands. The total area of the Baja California

History[edit] See also: Origin of the name California The land of California
California
existed as a myth among European explorers before it was discovered. The earliest known mention of the idea of California
California
was in the 1510 romance novel Las Sergas de Esplandián by Spanish author Garci Rodríguez de Montalvo. The book described the Island of California
Island of California
as being west of the Indies, "very close to the side of the Terrestrial Paradise; and it is peopled by black women, without any man among them, for they live in the manner of Amazons."[1] Following Hernán Cortés' conquest of Mexico, the lure of an earthly paradise as well as the search for the fabled Strait of Anián, helped motivate him to send several expeditions to the west coast of New Spain in the 1530s and early 1540s. Its first expedition reached the Gulf of California
Gulf of California
and California, and proved the Island of California was in fact a peninsula.[citation needed] Nevertheless, the idea of the island persisted for well over a century and was included in many maps. The Spaniards gave the name Las Californias to the peninsula and lands to the north, including both Baja California
Baja California
and Alta California, the region that became parts of the present-day U.S. states of California, Nevada, Utah, Arizona, and parts of Colorado
Colorado
and Wyoming.[citation needed] Timeline[edit]

1532: Hernán Cortés

before being killed. 1539: Francisco de Ulloa explores both coasts. 1690s–1800s: Spanish settlement and colonization in lower Las Californias ( Baja California

peninsula), the first Spanish missions in Baja California
Baja California
are established by Jesuit

missionaries. 1701: The first report and a map showing California

as a peninsula rather than an island is sent to Europe. 1767: Jesuits expelled; Franciscans

take over the Baja missions. 1769: Franciscans

go with the Portola expedition

to establish new missions in Alta California. Control of the existing Baja missions passes to the Dominican Order. 1773: Francisco Palóu's line demarcates Franciscan and Dominican areas of mission control. 1804: Las Californias divided into Alta ("Upper") and Baja ("Lower") California, using Palóu's line. 1810–1821: Mexican War of Independence 1821: First Mexican Empire, Baja California

Territory established, covering Baja California

cedes Alta California
Alta California
to the United States. As a U.S. territory it receives the California

Gold Rush, causing increased maritime traffic along the peninsula. 1850: California

admitted to U.S. statehood. 1853: William Walker, with 45 men, captures the capital city of La Paz and declares himself President of the Republic of Lower California. Mexico

forces him to retreat a few months later. 1930–31: The Territory of Baja California
Baja California
is further divided into Northern and Southern territories (North Territory of Baja California & South Territory of Baja California). 1952: The North Territory of Baja California
Baja California
becomes the 29th State of Mexico, Baja California. The southern portion, below 28°N, remains a federally administered territory. 1973: The 1,700 km (1,100 mi) long Trans-Peninsular Highway (Mexican Federal Highway 1), is finished. It is the first paved road that spans the entire peninsula. The highway was built by the Mexican government to improve Baja California's economy and increase tourism.[2] 1974: The South Territory of Baja California
Baja California
becomes the 31st state, Baja California
Baja California
Sur.

Political divisions[edit]

The province of the Californias was united until 1804, in the Spanish colonial Viceroyalty of New Spain, when it was divided into Alta (upper) and Baja (lower) California. The two Californias division was kept after Mexican independence in 1821. The Spanish Baja California
Baja California
Province became Mexican Baja California
California
Territory, and remained a separate territory until 1836. In 1836, the Siete Leyes

constitutional reforms reunited both Californias in the Departamento de las Californias. After 1848, the Baja California

was once a part of the North American Plate, the tectonic plate of which mainland Mexico

remains a part. About 12 to 15 million years ago the East Pacific Rise

began cutting into the margin of the North American Plate, initiating the separation of the peninsula from it. Spreading within the Gulf of California consists of short oblique rifts or ridge segments connected by long northwest trending transform faults,[4] which together comprise the Gulf of California

Rift Zone. The north end of the rift zone is located in the Brawley seismic zone in the Salton Sea

basin between the Imperial Fault and the San Andreas Fault.[4] The Baja California Peninsula

Researchers from Scripps Institution of Oceanography
Scripps Institution of Oceanography
have found a 2,000-year-old layer of non-decomposed roots, or peat, up to four meters (13 feet) under the desert mangroves. The peat layer acts like a sponge for stored atmospheric carbon, a record of sea-level-rise is also recorded in the peat layer. The desert mangroves restricted to rocky inlets on the rugged coast of Baja California
Baja California
have been growing over their own root remains over thousands of years to compensate for sea-level rise, accumulating a thick layer of peat below their roots. However, mangroves in flat coastal floodplains have accumulated a thinner peat layer.[6] Geography[edit] See also: Category:Natural history of Baja California

millions of years ago all along the margin of North America.

The Sierra de Juárez is the northernmost range in Mexico. The Sierra San Pedro Mártir

forms an isolated mountain range rising to 2406 m. Another isolated range, the Sierra Vizcaino, juts out into the Pacific between Punta Eugenia

and Punta Abreojos.

The two most prominent capes along the Pacific coastline of the peninsula are Punta Eugenia, located about halfway up the coast, and Cabo San Lazaro, located about a quarter of the way north from Cabo San Lucas. The Bahia Sebastian Vizcaino, the largest bay in Baja, lies along the Pacific coast halfway up the peninsula. The large island of Isla Cedros is situated between the bay and the Pacific, just north of Punta Eugenia. Onshore southeast of the bay is the Desierto de Vizcaino, an extensive desert lying between the Sierra Vizcaino to the west, and the Tres Virgenes

range which runs along the Gulf of California
California
to the east. The largest bays along the coastline of the Gulf are Bahia de La Paz where the city of La Paz is located, and Bahia Concepcion. The Bahía de los Ángeles is a small bay located west of the Canal de las Ballenas which separates the Baja California

peninsula from the large island of Angel de la Guarda

Most of the peninsula is deserts and xeric shrublands, although pine-oak forests are found in the mountains at the northern and southern ends of the peninsula. The southern tip of the peninsula, which was formerly an island, has many species with affinities to tropical Mexico.

Tourism[edit] The peninsula is known colloquially as Baja by American and Canadian tourists, and is renowned for its natural beauty and pristine environment. It draws ecotourists who go whale watching for migrating California
California
Gray Whales as well as tourists that arrive to the Baja California
California
Gold Coast and resorts on the southern tip of the Peninsula. Its location between the North Pacific

and Gulf of California
