The North America Portal
North America is a continent in the Earth's northern hemisphere and western hemisphere. It is bordered on the north by the Arctic Ocean, on the east by the North Atlantic Ocean, on the southeast by the Caribbean Sea, and on the south and west by the North Pacific Ocean; South America lies to the southeast. It covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 4.8% of the planet's surface or about 16.5% of its land area. As of July 2008, its population was estimated at nearly 529 million people. It is the third-largest continent in area, following Asia and Africa, and the fourth in population after Asia, Africa, and Europe. North America and South America are collectively known as the Americas or simply America.
North and South America are generally accepted as having been named after the Italian explorer Amerigo Vespucci, who explored South America between 1497 and 1502, and was the first European to suggest that the Americas were not the East Indies. Scientists have several theories as to the origins of the early human population of North America. The indigenous peoples of North America themselves have many creation myths, by which they assert that they have been present on the land since its creation. Before contact with Europeans, the natives of North America were divided into many different polities, from small bands of a few families to large empires. They lived in several "culture areas", which roughly correspond to geographic and biological zones and give a good indication of the main lifeway or occupation of the people who lived there.

The California Gold Rush
(1848-1855) began on January 24, 1848, when gold
was found by James W. Marshall
at Sutter's Mill
in Coloma, California
. The first to hear confirmed information about gold in California were residents of Oregon
, the Sandwich Islands (Hawaii
), western Mexico
, and Central America
. They were the first to go there in late 1848. All told, the news of gold brought some 300,000 people to California
from the rest of the United States
and abroad. Of the 300,000, approximately half arrived by sea and half came overland from the east, on the California Trail
and the Gila River
The effects of the Gold Rush were substantial. San Francisco grew from a small settlement of about 200 residents in 1846 to a boomtown of about 36,000 by 1852. Roads and other towns were built throughout California. In 1849 a state constitution was written, and a governor and legislature were chosen. California became a state as part of the Compromise of 1850.
The planes that serve as Air Force One can be operated as a military command center in the event of an incident such as a nuclear attack. Operational modifications include aerial refueling capability, electronic countermeasures (ECMs) which jam enemy radar, and flares to avoid heat-seeking missiles. The heavily shielded electronics onboard include around twice the amount of wiring found in a regular 747.
