The Pike's Peak Gold Rush, which followed the California Gold Rush by approximately one decade, produced a dramatic but temporary influx of migrants and immigrants into the Pike's Peak Country of the Southern Rocky Mountains. The rush was exemplified by the slogan "Pike's Peak or Bust!", a reference to the prominent mountain at the eastern edge of the Rocky Mountains that guided many early prospectors to the region westward over the Great Plains. The prospectors provided the first major European-American population in the region.
