Abandoned Mine Sites
Abandoned mine shaft
Several abandoned mines are scattered throughout the park. Use extreme caution in areas around mine sites. Watch out for sharp rusted pieces of old mining equipment. Abandoned chemicals such as cyanide, arsenic, mercury and other deadly toxins may also be present in leaky and deteriorating containers. Don’t drink the water in areas near mine sites – filtering or treating it will not remove arsenic, mercury or other heavy metals that may be present.
Never enter an adit, mine shaft or tunnel! They are extremely unstable and cave-ins and falling debris are a real danger. Darkness and debris in old mines can make it difficult to identify hazards such as rotted boards, hidden holes and deep shafts. Lethal concentrations of dangerous gasses can accumulate in underground passages and oxygen deficient air can cause rapid suffocation.
