The best-known gold rush in modern history occurred in California in 1848, when James Marshall discovered gold in Sacramento Valley. As word spread, thousands of migrants flocked to California in search of gold, and by 1855, miners had extracted around $2 billion worth of gold. The United States, Australia, and Russia were (interchangeably) …
