Bunker Hill Smokestack Demolition Marks 30 Years in Silver Valley History
Tuesday, May 27, marks three decades since one of the most recognizable landmarks in Silver Valley came down. The Bunker Hill lead smelter smokestack, a towering fixture of the industrial landscape near Smelterville, was demolished on May 26, 1996, closing a visible chapter in the region’s long mining history.
The stack had stood as a symbol of the Bunker Hill Company, once one of the largest lead and zinc smelting operations in the United States. Its demolition followed years of decline after the complex shut down in the early 1980s, a closure that dealt a severe economic blow to Shoshone County and the broader Silver Valley community.
The site later became central to one of the nation’s largest Superfund cleanup efforts. Silver Valley’s mining legacy carries a complex lead contamination history that has shaped the region’s identity and environment for generations. The ancient geological processes that built Idaho’s Silver Valley created the mineral wealth that drew industry — and the consequences that followed.
What Comes Next
As the Silver Valley continues its economic and environmental recovery, the 30-year anniversary of the stack’s demolition offers a moment to reflect on a heritage that remains central to Shoshone County’s identity. Community members and historians are encouraged to share memories and photographs from that era.
