Tuesday, May 26, marked the 30th anniversary of the demolition of the Bunker Hill smokestack, one of the most recognizable industrial landmarks in Shoshone County and the broader Silver Valley region of northern Idaho.
The towering stack, long associated with the Bunker Hill lead and zinc smelting complex near Smelterville, stood for decades as a symbol of the mining and smelting industry that built communities across the Silver Valley. Its 1996 demolition marked a visible turning point in the region’s transition away from heavy industrial smelting operations.
The Bunker Hill site and surrounding areas have since become central to one of the nation’s largest Superfund cleanup efforts, tied to decades of lead contamination across the valley. The smokestack’s fall remains a defining moment in local memory, representing both the end of an industrial era and the beginning of a long environmental remediation process.

What Comes Next
Cleanup and redevelopment efforts at the former Bunker Hill site continue, with ongoing federal and state oversight of the Superfund area. Community leaders and historians in Shoshone County continue to preserve the industrial heritage of the Silver Valley as the region looks to recreation, mining, and small business for its economic future.
