Avoid the steep slopes where loose debris is present. Please keep to the gravel paths. Do not attempt to walk on decks or stairs attached to the buildings. Many of the boards are rotten and unsafe. The Kennecott Copper Corporation conducted hazardous materials clean up of asbestos, oils and other materials between 1990 and 1993.
Lead contamination is still present in the paint covering the buildings.
Removal of the lead hazards is planned for the upcoming summers. If hiking to one of the mine sites, be aware that these same hazards exist. Often, these buildings are in a much greater state of disrepair and are more prone to collapsing than the mill site buildings. The mines themselves are collapsing and are extremely dangerous. Please keep children under close supervision.
