Boomtowns are built on optimism; ghost towns are what's left when it runs out. Welcome to Cardinal. A ghost town of unknown status in Boulder County, Colorado.

Colorado's high-country ghost towns sit at altitudes that would give a flatlander nosebleeds — silver camps killed by an 1893 vote in Washington.

Boulder County holds 6 documented ghost towns, including Caribou, Eldora, Hessie — Cardinal keeps them company on the map.

The story of Cardinal

Colorado's mountains are a timeline of American mining law written in wood and stone. The Pikes Peak rush of 1859 started it; the silver boom of the late 1870s — Leadville, Aspen, Creede — turned the high country's mineral districts into some of the richest on earth. Then came 1893: the repeal of the Sherman Silver Purchase Act crashed the price of silver overnight, and Colorado's silver camps died in a matter of months. It remains the single fastest mass-abandonment in the state's history. Cardinal is a product of that cycle — built on a metal whose value was set in Washington, emptied by a vote it never saw coming.
