Founded 166 years ago in 1859 by prospectors during the early days of thePike's Peak Gold Rush, the town was at the center of the region's mining district throughout the late nineteenth century. TheArgo Tunnel drained and provided access to many lodes of ore between Idaho Springs andCentral City. During the late twentieth century, the town evolved into a tourist center alongU.S. Highway 6 andU.S. Highway 40, which ascend Clear Creek Canyon through the historic mining district.
The town today is squeezed along the north side ofInterstate 70, with a historical downtown in the central portion, a strip of tourist-related businesses on its eastern end, and mostly residences on its western end. It also serves as abedroom community for workers at theLoveland Ski Area farther up the canyon. The town today is the largest community in Clear Creek County, but, for historical reasons, the county seat has remained atGeorgetown.
On January 5, 1859, during theColorado gold rush, prospector George A. Jackson discoveredplacer gold at the present site of Idaho Springs, where Chicago Creek empties intoClear Creek. It was the first substantial gold discovery in Colorado. Jackson, aMissouri native with experience in theCalifornia gold fields, was drawn to the area by clouds of steam rising from some nearbyhot springs. Jackson kept his find secret for several months, but after he paid for some supplies with gold dust, others rushed to Jackson's diggings.[9] The location was originally known as "Jackson's Diggings". Once the location became a permanent settlement, it was variously called "Sacramento City", "Idahoe", "Idaho", "Idaho City", and finally "Idaho Springs".[10]
The first placer discoveries were soon followed by discoveries of gold veins in the rocks of the canyon walls on both sides of Clear Creek.Hard rock mining became the mainstay of the town long after the gold-bearing gravels were exhausted.
TheIdaho Springs miners' strike of 1903 demanding aneight-hour day erupted into violence in May 1903. This was a conflict was a part the much broaderColorado Labor Wars, where the Western Federation of Miners sought to pressure mining companies into improving conditions for miners.
