In reply to Rollo Jones:
Bear in mind that there have been some major rockfalls in the last decade, and that most of the north side of the Trolltindene is very serious (not very good rock, and on a huge scale) The Trolltind wall and the area immediately left and right of it is like a rather unfriendly, north-facing version of El Cap, made of much inferior rock, and with a quite bad cyclonic climate.
