In the United States, abandoned mines still hide across deserts, mountains, forests, and public land: open shafts, flooded pits, collapsed tunnels, and unstable ground left behind by gold rushes, hard-rock mining, and coal extraction. In this episode, we trace the dark history of abandoned mines from California and Nevada to Colorado and Appalachia, and ask a harder question beneath it all: when people vanish in remote country, how often is the answer under their feet?

From Joshua Tree and Twentynine Palms to Nevada and West Virginia, this episode follows real deaths, disappearances, and recoveries tied to old mine country while looking at the larger hazard footprint still spread across the United States. It’s a story about ghost landscapes, forgotten industry, and the deadly holes America never really closed.
