Gold!
January 24, 2013 | SuzyQ
165 years ago, on January 24, 1848, gold was discovered at Sutter's Mill setting off the California Gold Rush. People began flocking to the state later that year, but the majority didn't arrive until the next year — hence the term "forty-niners." All told, the news drew some 300,000 people from all over the world (Latin America, Europe, Australia and China) between the years 1849 and 1855, to seek their fortune in California.
