New England Asbestos
New England has never been a major mining region and asbestos is a relatively uncommon mineral, but in America's early days small mines and quarries often successfully supplied local needs for many years.

One has to wonder how many of the early prospectors and miners who worked these small deposits died of lung cancer, mesothelioma, and asbestosis.
