Abandoned mines and quarries are dangerous places! In a typical year, several people die in accidents that occur in abandoned mines across the United States. Some of these deaths can be prevented if citizens know the danger of these properties; if landowners make better efforts to warn and limit access; and, if governments have improved programs for reclaiming or regulating them.

If you are a mineral collector, hiker, recreational vehicle rider, swimmer, or curious person, you have no business entering an abandoned or inactive mine or quarry. In almost every instance, you will be trespassing because abandoned mines and quarries are almost always on private property.
