This is a slight variation on Mr Mike's original idea:flowers:

I have no idea what is it or where it is, but a sizeable operation.
Possibly taken in the 80's as the processing plant looks newish (1970's corrugated panels?) and in use given that are there several cars visible on another pic of the same place. There is a lot of tipped waste which suggests a quarry or open-casting. Clearly a bit hilly so could be N. Wales, Lakes or Scotland, the mountain in the background would be a bit of a help for someone who has an idea. My current guess is Scotland as parents spent several summers up there in the 80's and 90's.
