Fig. 1.— THE FAULT-BLOCKS EAST OF CATHEDRAL PEAK 
FROM THE KEDONG VALLEY. 
Cathedral Peak is seen to the extreme right, over a fault-block, west of the Kedong ; the 
hills to the south are composed of lava tilted down to the west (the right of the photograph) 
by six parallel faults. The hills consist of trachytic lavas and tuffs.
