Why Idaho Springs exists: an 1859 gold strike
Idaho Springs grew up around an early 1859 gold discovery on Clear Creek that helped launch Colorado's gold rush.

Most Colorado mountain towns exist for a reason, and for Idaho Springs the reason is gold. In early 1859, a prospector named George Jackson found gold along Clear Creek near where the town now sits. Word spread fast, and his find became one of the sparks of the gold rush that pulled thousands of people into the Rockies that year.
That rush is sometimes called the Pike’s Peak gold rush, even though much of the action happened in the mountains west of Denver, including here in what became Clear Creek County. A second major strike that same season near Central City pulled in even more miners. Together they put this stretch of the mountains on the map.
A camp grew at Jackson’s site, and that camp became Idaho Springs. The town also gained a name for its warm mineral springs, which gave people another reason to come and stay. So the place was shaped by two things people wanted out of the ground: gold and hot water.
Knowing this helps explain the town’s layout and old buildings today. It was built quickly by people chasing a discovery, then held on long enough to become a lasting community.
