Asbestos was mined in Vermont, being one of two states rich with the mineral. The other was California (most North American asbestos came from Canada). The principal Vermont asbestos mining area is on Mt. Belvedere, in the northern part of the state. Mining started in 1889, and by 1930, nearly all asbestos in the nation came from here. It closed in 1993. Here we have an unusually green grossular in a bed of massive diopside. Locality: Vermont Asbestos Company Quarry, Eden Mills, Vermont
