Where I live (lake District) there are a large number of Surface & underground slate workings, typicallly forming chambers. Anyone know what the slate workings in NorthEast america?

Slate is found in several northeastern states. There are/were mining operations around the border of New York/Vermont and Eastern Pennsylvania. A map of the Pennsylvania slate regions is at:

There are three slate quarries still operating in the slate belt of Pennsylvania. These are all open pits and served by cableways. Historical examples of these quarries can be seen in the photos at:

Traditional chambers were not used in the slate belt of Pennsylvania. The closest example was at the now filled Parsons Quarry. It was a traditional open pit that was extended horizontally to form a chamber so that slate could be mined from under an adjacent railroad right of way. The railroad even received a royalty for every block of slate mined below their tracks.
