Ghost Towns of Colorado
Colorado's dead towns map its ore: silver camps killed en masse by the 1893 crash, gold towns that outlived them by a decade, and high-altitude settlements where winter finished whatever the markets started.
584 sites surveyed across Colorado — 13 charted with full records so far, entered by year of settlement. The rest are awaiting verification.
Survey note
The federal place-name archive records 584 vanished or historical sites in Colorado — ghost towns, mining camps, townsites, and railroad stops. We chart them a few at a time, as the records can be verified. Every mark on this map is a place that once had a name.
