Among the settlers pouring into Indian Territory in the Rocky Mountains were miners in search of gold and silver. These prospectors envisioned instant riches that would come from a lucky strike. The vast majority found only backbreaking work, danger, and frustration. Miners continued to face hardship and danger as industrial mining operations took over from individual prospectors, despite the efforts of some miners to fight for better wages and working conditions. By 1900 the mining rush had peaked, and many of the boomtowns that had cropped up around the mining industry had emptied out. Still, mining companies and the workers they attracted forged big cities of diverse peoples and commerce. Closely related to mining, the lumber industry was less demographically diverse but also followed the pattern of domination by big business.
