Gold Rush-era towns emerged in the mid-19th century during the California Gold Rush and other similar events across the United States. These towns were often quickly established as prospectors flocked to areas where gold was discovered, leading to rapid population growth and economic activity. Many towns featured wooden buildings, saloons, and general stores, catering to the needs of miners and their families. As gold became harder to find, many of these towns experienced decline, with residents moving on in search of new opportunities. Some towns, like Virginia City and Deadwood, became famous for their colorful histories and are now preserved as historical sites, attracting tourists interested in the Wild West era.
