The mountain Brunnhorn (454 m) is located in southeast Iceland near Höfn. Some refer to it as Batman Mountain and you can see why from the images. Brunnhorn is an extension of its famous neighbour Vesturhorn.
Both the mountains are “a batholite made of gabbro, with high cliffs and steep screes.” (vide Iceland Road Atlas).
