2. Virginia City, Nevada

In 1859, the discovery of the Comstock Lode, a rich deposit of silver ore, transformed Virginia City into one of America’s wealthiest towns almost overnight. The mining boom attracted thousands, including Samuel Clemens, who began his writing career as a reporter under the pen name Mark Twain. Although the silver eventually ran out, Virginia City remains a bustling tourist destination, offering a glimpse into its storied past. (nps.gov)
