So named after the magnitude 7.1 Arthur’s Pass earthquake on 9 March 1929, which caused the total collapse of the mountain’s 900-metre high northwest side.
Start from the head of the Edwards Valley near Taruahuna Pass. Other routes
may be taken from near Taruahuna Pass and Tarn Col on the Otehake side of the
mountain. Beware of major rockfall problems across the entire northwest face.
