Bastion mountain from the west, showing the Sicamous lime- 

 stone (in the high bluff) overlain by the Bastion schists 

 (background, on the left). The large out crop near the 

 middle of the view is intrusive syenite 125 



Aplitic and pegmatitic sills cutting rusty metasedimentary schists 

 and limestone interbeds; Shuswap terrane, western shore of 

 Mara Arm of Shuswap lake 127 



Schistose structure of typical orthogneiss in Shuswap terrane, 

 illustrating static metamorphism. The hammer is about 

 32 cm. in length. Locality, Albert Canyon station 129 



Strain-slip cleavage in talc schist of the Shuswap series, at Blind 

 bay. The well developed, low-dipping schistosity is due to 

 earlier static metamorphism. Camera case about 7 cm.
