These maps (numbered 1 to 180) show the location of rock sources in the Port Hills and also where rocks have fallen as a result of the 2010/11 Canterbury earthquakes.
The key on these maps describes areas of Bluff Talus (where debris has fallen from a bluff), Bluff Insitu (the location of a particular bluff) and Bluff Envelope (the general location of a bluff that is too dangerous to allow closer inspection to be carried out).
