By the way Canmore is being retired in June and replaced by a new site TROVE (not to be confused with the Australian newspaper archive which is also called TROVE).

It involved a long walk to the top of some VERY high cliffs. At the bottom was a cave that was being eroded away and bones etc scattered on the shore.
