It’s no accident that Denver is called “the Mile High City”: When you climb up to the State Capitol, you’re precisely 5,280 feet above sea level when you reach the 13th step. Denver’s location at this altitude was purely coincidental; Denver is one of the few cities not built on an ocean, a lake, a navigable river, or even (at the time) an existing road or railroad.
In the summer of 1858, eager prospectors discovered a few flecks of gold where Cherry Creek empties into the shallow South Platte River, and a tent camp quickly sprang up on the site. (The first permanent structure was a saloon.) When militia Gen. William H. Larimer arrived in 1859, he claim-jumped the land on the east side of the Platte, laid out a city, and, hoping to curry political favors, named it after James Denver, governor of the Kansas Territory, which included this area. The plan didn't exactly work: Larimer was not aware that Denver had recently resigned.
Larimer’s was one of several settlements on the South Platte. Three others also sought recognition, but Larimer had a solution. For the price of a barrel of whiskey, he bought out the other would-be town fathers, and the name "Denver" caught on.
Although the gold found in Denver was but a teaser for much larger strikes in the nearby mountains, the community grew as a shipping and trade center, in part because it had a milder climate than the mining towns it served. A devastating fire in 1863, a deadly flash flood in 1864, and American Indian hostilities in the late 1860s created hardship, but the establishment of rail links to the east and the influx of silver from the rich mines to the west kept Denver going. Silver from Leadville and gold from Cripple Creek made Denver a showcase city in the late 19th and early 20th centuries. The U.S. Mint, built in 1906, established Denver as a banking and financial center.
In the years following World War II, Denver mushroomed to become the largest city between the Great Plains and the Pacific Coast, with almost 600,000 residents within the city limits and over three million in the metropolitan area. It remains a growing city, with a booming downtown and suburbs. Denver is noted for its tree-lined boulevards, 200 city parks that cover more than 20,000 acres, and architecture ranging from Victorian to postmodern.
