Kilometres remnant of the uplifted Tertiary peneplain. 

 Its southern slope is a fault line scarp, developed 

 along the eastward continuation of the fault 

 mentioned above. 



34-4 m. Koksilah — Altitude 28 ft. (9 m.). 



55-4 km. 



37-0 m. Cowichan — Altitude 119 ft. (36 m.). 



59-6 km. 



38-4 m. Hillbank — Altitude 150 ft. (46 m.). North 



61 -S S km. of Cowichan is a quarry in the Nanaimo 

 sandstones, which are seen to be underlain by 

 shales. The last exposures of the Nanaimo 

 sandstones are seen to the north of Hillbank. 



41 -3 m. Cobble Hill — Altitude 315 ft. (96 m.). To 



66-5 km. the west of Cobble Hill station is Cobble hill, 

 1,100 feet (355 m.) high, which with the excep- 

 tion of the northern slope underlain by Saanich 

 granodiorite, is composed of Vancouver meta- 

 volcanics, which form a belt 2 to 20 miles 

 (3 to 30 km.) wide extending to the west coast. 

 Numerous outcrops of the volcanics are seen 

 near the railroad to the south of Strathcona 

 and along the northern shore of Shawnigan lake, 

 although the volcanics are largely covered by 

 Vashon till. Just to the south of Strathcona 

 is a small lentil of Sutton limestone which is 

 intercalated in the Vancouver volcanics.

Strathcona — Altitude 456 ft. (139 m.). 



25 Mile Post— Altitude 553 ft. (168 m.). 

 Shawnigan lake has been formed in the glacially 

 deepened portion of one of the mature, trans- 

 verse, north-south valleys, which dissect the 

 uplifted Tertiary peneplain. From Koenig the 

 railroad climbs rather rapidly up the steep 

 east slope of the Shawnigan Lake valley to 

 the pass east to the next transverse north-south 

 valley.
