Shafts of Light over Iona

This was taken during today's workshop from Loch na Keal looking towards the Ross of Mull and Iona. One of my guests referred to these shafts of light as "angels' slides". An appropriate description perhaps given that they were directly over Iona. I've heard them various referred to as crepescular rays and god rays but never as angels' slides. What a lovely phrase.
