History & Asbestos Use
Asbestos mining on Belvidere Mountain dates to the 1890s, with large-scale commercial operations beginning in the 1930s. The Vermont Asbestos Group operated the mine through its final decades, producing chrysotile fiber primarily for the Canadian and American markets. It was the last asbestos mine to close in the United States, shutting down in 1993 as demand collapsed under regulatory pressure and liability concerns.
