The Whangie in the north of the Kilpatricks is of particular interest to geologists and casual walkers alike. It consists of a slice of the hillside that has been separated from the main slope. This has created a narrow chasm up to 10 metres (33 ft) high and about 100 metres (330 ft) in length through which visitors can walk. It has commonly been explained as result of glacial plucking, but more recent research indicates that a translational landslide was the cause. During an ice age, a glacier slowly undermined the crag, opening up cracks in the rock and causing this chasm to form.
