Colorado's Rich Mining Legacy
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 gases, 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. We encourage you to learn more about mining and Colorado's historic mining past by visiting a mining museum or tourist mine in Colorado.
