History

Eldora was first settled by the Arapaho- and Ute people who used the area for hunting during summer. Eldora was originally built as a mining town. Although prospectors had been poking around in Eldora since the early 1850s, it was not until 1875 that enough gold was discovered to open a mine in Eldora. The primary decision to officially establish a town in the 1880s was in part an effort to open up further mining area, and in part an attempt at a through route into Middle Park and Western Colorado. Eldora boomed and prospered during the 1890s, and at one point, Eldora was home to as many as 1300–1500 people in the late 1890s. In 1898, Eldora was home to a bank, a post office, a school, nine hair saloons and seven grocery stores. Although it had a mining life of its own, Eldora also served as a supply center for the camps beyond, and a rail-road shipping center for the camps in the nearby area. The first time the manager of the Bailey Chlorination Mill in Eldora, Mr. Bailey, neglected to pay his workers on time, angry employees promptly gathered at his house, smoked him out, and shot and killed Mr. Bailey. Despite its intensity of gold, silver and tungsten mining, Eldora’s economic boom was brief. It peaked at the turn of the century, but experienced a devastating wildfire in 1899. With much of its timber lost, lumber that was vital to the mining construction was in short supply. The 21st century has experienced renewed interest in Eldora mining, with hopes of reopening the Mogul Tunnel Mine on Spencer Mountain.
