Hidden within the steep slopes of the Black Hills in Jerome, Arizona, the Gold King Mine stands as a notorious landmark in the American West. For over a century, this site operated as a productive gold and silver producer, leaving behind a complex legacy of mineral wealth and environmental consequence. Its story is deeply intertwined with the boom-and-bust history of Jerome, a town that famously slid down a mountainside while chasing the ore beneath it.
The Historical Operations of the Gold King Mine
Active primarily during the late 19th and early 20th centuries, the Gold King Mine was part of the rich mineral belt that defined the Jerome Mining District. Miners extracted significant quantities of gold, silver, copper, and zinc from the fractured veins of rock. The operation utilized traditional hard-rock mining techniques, involving tunneling and blasting to reach the valuable deposits located deep within the mountain. This period of intense extraction fueled the economy of Jerome and populated the surrounding wilderness with the infrastructure of industry.
Jerome: The Town That Clung to the Mountain
The history of the Gold King Mine is inseparable from the story of Jerome, often called the "Wickedest Town in the West." Built on the steep slopes of Cleopatra Hill, Jerome was a bustling mining camp notorious for its saloons, brothels, and rough-and-tumble population. As the mine shafts delved deeper, the town above gradually shifted and slumped, creating the surreal sight of buildings tilting at precarious angles. The Gold King Mine was one of the many operations that supported this vertical city, its headframes and tunnels contributing to the literal shifting of the ground beneath the residents' feet.
Environmental Consequences and the Acid Mine Drainage Issue
Long after the last ore cart was pulled to the surface, the Gold King Mine became a source of significant environmental concern. Like many abandoned mines in the region, it began to release acidic water, a process known as Acid Mine Drainage (AMD). When exposed air and water react with sulfide minerals left in the waste rock, they generate sulfuric acid, which then leaches heavy metals—including arsenic, cadmium, and lead—from the surrounding rock. This toxic cocktail flows untreated into local waterways, posing a serious threat to the ecosystems of the Verde River watershed.
The 2015 Spill Event
On August 5, 2015, the legacy of the Gold King Mine took center stage in a national news story. While the Environmental Protection Agency (EPA) was conducting a cleanup investigation at the site, a drainage tunnel collapsed, releasing an estimated 3 million gallons of contaminated orange water into the Animas River. The spill turned the river a distinct mustard color and carried pollutants downstream through Colorado, New Mexico, and Utah. This event thrust the forgotten mine into the spotlight, highlighting the ongoing challenges of cleaning up America’s vast inventory of abandoned mines.
Modern Remediation and Current Status
In the years following the 2015 incident, the Gold King Mine has been the target of extensive stabilization efforts. The EPA installed a bulkhead—a large concrete seal—at the main entrance of the mine to control the flow of contaminated water. This was followed by the construction of a water treatment plant designed to neutralize the acidity and capture heavy metals before the water reaches the Animas River. These engineering solutions aim to mitigate the environmental damage while allowing the site to be safely managed for the future.
Visiting the Site and Cultural Significance
Today, the Gold King Mine remains on private land and is not open to the general public due to the ongoing environmental hazards and safety concerns. However, its presence looms large over the town of Jerome, which has successfully transformed itself into a tourist destination centered on art, history, and wine. Visitors to Jerome can explore the steep streets, visit the Jerome State Historic Park, and view the remnants of mining operations from a safe distance. The Gold King Mine serves as a powerful reminder of the cost of extraction and the importance of environmental stewardship in the American West.
