                                                  Pillow lava

                                                  Pillow lava in the Bencorragh Formation, on the
                                                  summit of Bencorragh. Note how the keel of the
                                                  pillow at centre right has moulded into the gap between
                                                  the two lower pillows (compass for scale).

                                                  peneplain; small outliers of Carboniferous sandstone remain on top.
