—————
The first Leadville boom took place in the early 1860's with the discovery of rich placer gold diggings, but the surface deposits were quickly exhausted. The second boom in the 1870's ushered in the silver era. One of the most spectacular strikes in Colorado mining annals, it began with a series of incredibly rich discoveries along California Gulch. Almost overnight the desolate pine flat just below timberline sprouted into a rowdy, rugged mining camp with the usual assortment of pine bough shelters, tent hotels, banks, grocery stores, beer gardens, and mine dumps. The extravagance and gaudy taste of the richest miners equaled or surpassed that of their counterparts in other mining camps.
In 1880, Leadville's population was estimated at from 25,000 to 40,000 and it was proud of its reputation as a wide-open mining town, with 100 licensed saloons and a dozen gambling houses operating around the clock. It has been estimated that the district produced some $136,000,000 in silver between 1879 and 1888.

strata, quartz veins heavily seamed with gold were discovered, and in spite of the panic of 1893, which ended the silver boom, Leadville prospered again as a gold camp until the end of the century. Since that time, lead, zinc, manganese, and molybdenum have been mined in the district.
Leadville, today, is one of the largest of the old mining towns. The north side of the town has been developed with modern commercial and residential buildings. There remain, however, along the Harrison Avenue corridor, a number of historic structures. The Leadville Historic District encompasses a scattered group of distinctive and important historic buildings of the central architectural theme associated with late 19th-century mining towns of the West.
