High up in a quiet corner of Glen Etive is a large boulder, and improbably anchored on top of that boulder is a rowan tree. It stands in a beautifully isolated but prominent position on a tongue of land between two burns and, as you climb higher onto Stob Dearg this oddity, bowed in deference towards the Buachaille, feels like a sentinel guarding the entrance to the upper coire. I have a list of favourite natural oddities in Scotland but this tree / boulder combo is up there with the best. I love it because it just looks plain weird…
