New Idria California Ghost Town: A Toxic Legacy of California’s Past

Deep in the heart of California lies a toxic remnant of the state’s mining history. The New Idria California Ghost Town, once a bustling hub of mercury production, now stands abandoned and crumbling. The mine, which operated from 1854 to 1972, left a lasting impact on the environment and the lives of those who once called this place home.

This article delves into the captivating history of New Idria, California Ghost Town, its rise and fall, and the ongoing efforts to address the environmental hazards left behind.

A Brief History of New Idria California Ghost Town

The Beginning: A Mining Boom

The story of New Idria, California Ghost Town begins in 1854, with the discovery of cinnabar, a mercury-rich ore, in the southern Diablo Range of central California. This discovery came at a crucial time, as mercury was an essential component in the extraction of gold during the California Gold Rush.

The New Idria Mining Company was formed, and the town of New Idria was established to support the mine’s operations.

At its peak, the New Idria mines were the second most productive mercury mines in the United States, with the nearby New Almaden mines ranking first. The town grew to support the mining operations, boasting shops, a post office, a school, and a church.

The mine was named in honor of the world’s then second-largest quicksilver mine in Idrija, Austria (now Slovenia).

The Decline: Environmental Hazards and a Ghost Town Emerges

The New Idria mine was eventually shut down in 1972, and the town’s livelihood disappeared. The once-thriving community was left abandoned, and over time, more than 100 buildings fell into disrepair.

Vandalism contributed to these structures’ deterioration; in 2010, a fire destroyed 13 buildings on the north side of the town.

In the decades following the mine’s closure, concerns regarding contamination in the area began to surface. Investigations in the 1990s by the Environmental Protection Agency (EPA) revealed alarming levels of mercury and other toxic chemicals in the town and surrounding areas.

By 2011, the EPA re-listed New Idria as a Superfund site due to unchecked mercury run-off and contamination. The entire section of the former town site on the south side of New Idria/Clear Creek road is now fenced off, and the area is deemed an Asbestos Hazard Area.

The Toxic Legacy: Environmental Concerns and Cleanup Efforts

Mercury Contamination

The most significant environmental concern in New Idria is the mercury contamination from its mining operations. The area contains three forms of mercury, including the most hazardous: monomethyl mercury, a neurotoxin.

Water from the local San Carlos and Panoche creeks discharges the heavy metal, carrying toxicities up to 20 miles downstream.

Asbestos and Other Hazards

In addition to mercury contamination, the New Idria area is plagued by high asbestos levels due to the natural serpentinite rock formations in the region. The 2010 edition of Rand McNally’sThe Road Atlas labels the area immediately south of New Idria as an “Asbestos Hazard Area.”

The EPA’s 2004 Risk Assessment for the nearby Clear Creek Management Area identified 86 separate abandoned mines that mined asbestos and chromium. The natural rock formations in the area have been shedding asbestos-rich debris into stream valleys for millions of years, with the average New Idria rock containing 5-15% by volume short fiber asbestos.

Cleanup Efforts

Since being declared a Superfund site, cleanup operations have been underway in New Idria. However, the process has been slow, and the area remains toxic and uninhabitable. The EPA has been working on a plan to address the mercury contamination and other environmental hazards.

Still, as of now, there is no definitive timeline for when the cleanup will be completed.

A Glimpse Into the Past: Visiting New Idria California Ghost Town

Despite the environmental hazards and the site’s fenced-off status, some intrepid explorers have ventured into New Idria to glimpse its eerie past. The remnants of the town, including dilapidated homes, rusting mining buildings, and the abandoned extraction plant, offer a haunting window into the lives of those who once called this place home.

Visitors to the site have described an almost atmospheric anxiety, a feeling of dread heightened by isolation and the town’s intrinsic eeriness as a ghost town. For those who dare to venture into this toxic wasteland, the experience is both chilling and unforgettable.

It is essential to note, however, that visiting New Idria is not recommended due to the risks associated with mercury and asbestos exposure. The site remains fenced off and is considered hazardous to public health.
