The Pike's Peak Gold Rush (later known as the Colorado Gold Rush) is the boom in gold prospecting and mining in the Pike's Peak Country of western Kansas Territory and southwestern Nebraska Territory of the United States that begins in July 1858 and lasts until roughly the creation of the Colorado Territory on February 28, 1861.
An estimated 100,000 gold seekers take part in one of the greatest gold rushes in North American history.
The participants in the gold rush are known as Fifty-Niners after 1859, the peak year of the rush and often use the motto Pike's Peak or Bust!
