It certainly doesn't refer to all artificial cavities. In my experience (en-US), adits are always associated with mining, almost always with drainage--I think drifts and stopes are the proper terms for other horizontal passages. (Well, stopes can be large and hollowed-out, but I digress.) While "tunnel" might be used colloquially for anything you can move through underground, I think the commonly used and more correct term for a natural underground corridor is "passage" or "passageway". (e.g., "unusual features can be seen in the passage between the Crystal Room and Room Five".) -- Chris _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
