Hey Roger -

I do like photographic mysteries like this related to the trade and its variations...

Though I don't know if we can expect to figure out where this was shot, we can as you suggest, narrow it down some.

It is not here in NNE, nor anywhere else where stone walls dominate.

They are well outfitted and tooled up, that does suggest an area doing well, or in a cyclic boom-time or period of rapid growth.

The slate ripper might well be a clue, slate roofs tend to occur in geographic pockets.

The lack of conifers says something. Does anybody recognize the species pictured?
