San Francisco, California - a city both old and new. The area where San Francisco is currently situated was, according archeological evidence, 3000 BC by the Yelamu group of the Ohlone people until Spanish explorers arrived in 1769. The area is under Spanish rule for nearly 80 years until the area is claimed for the United States in 1846. The Gold Rush, beginning in 1848, drew people from all over America which grew the population from a mere 1,000 to 25,000 in just one year.
