 Kilometres. 



95 m. Harrison Mills — Alt. 40 ft. (12-2 m.). From 



152-8 km. Agassiz to the coast the railway runs through 

 the agricultural country of the delta, which is 

 everywhere covered with deep alluvium and, in 

 consequence, rock exposures are rare. The 

 whole delta is believed to be floored by deposits 

 of Eocene age, which are covered by Glacial 

 and post-Glacial deposits of the same character. 

 Knobs of granitic rocks and Lower Cretaceous 

 quartz porphyries project through the more 

 recent deposits. 



Harrison river is crossed at Harrison Mills, 

 and beyond, the railway curves around and be- 

 hind an outlying knob of these granitic rocks. 

 Hatzic — Alt. 30 ft. (9 -14m.). As far down 

 114 m. Mission — Alt. 21 ft. (6-4 m.). as the sea 



183-4 km. Silverdale. coast the 



railway skirts the southern base of the Coast 

 Range mountains, which are composed of the 

 granitic rocks of the Coast Range batholith. 

 Occasionally cuts are made into projecting 

 points, which show their character. At Silver- 

 dale a part of the old floor on which the 

 Eocene delta deposits were laid down is exposed. 

 This floor is presumably part of the Coast 

 Range batholith, and its deeply weathered 

 character indicates that it was long exposed to 

 the action of weathering before the deposition 

 of the Eocene deposits. The irregularity of 

 that old floor, and the attitude of the Eocene 

 deposits in relation to the adjacent mountains, 

 suggest also that during the deposition of those 

 deposits the neighbouring region of the Coast 

 range was then, as now, one of considerable 

 relief.
