Colorado’s mining history has left a rich legacy. However, this legacy also includes 23,000 inactive and abandoned mines that can be as dangerous as they are picturesque. Mine sites may look safe to explore, but they often contain unstable soil, unsafe roofs and ladders, deadly gasses, poisonous snakes and dangerous explosives. The Colorado Division of Reclamation, Mining and Safety asks you to “Stay Out and Stay Alive” and not explore abandoned mines.

Our Stay Out, Stay Alive informational video is available for viewing here.

Access the brochures below for additional information on our Stay Out, Stay Alive Campaign.

Last year 22 people died, nationwide, while exploring abandoned mines.

Victims of mining accidents have encountered deadly odorless gases, fell down holes that opened under their weight, drowned in near-freezing pools of water at the bottom of shafts, and were buried in unpredictable cave-ins.

Many people are injured and killed every year while "just exploring" abandoned mines. Don't be a victim.


Be Smart.  Stay Out.  Stay Alive.
