Asbestos was first mined in Vermont in 1899 on Belvidere Mountain. Chrysotile deposits of ultramafic rock were quarried in the Mt. Belvidere mines located in Eden and Lowell, Vermont. The mountain includes serpentinized ultramafic, coarse and fine-grained amphibolite, greenstone, and muscovite schist (see Marjorie Gale’s article on the Geology of Belvidere Mountain). The New England Asbestos Mining and Milling Company was organized around the turn of the twentieth century, and was the first company in the United States to mine asbestos. They began mining in Eden but discontinued operations in 1902. Quarrying and milling began again in the 1920s and by 1929, “the Eden-Belvidere Mountain mines were producing almost all of the asbestos in the United States, and were increasing production yearly” (Wallace, 1990, 4). In 1939, the mine was sold to the Vermont Product Corporation, a subsidiary of the Rubberoid Company, and the mine continued to prosper. By the 1960s, roughly 3500 tons of ore were mined daily.
