Choate — 

 65 m. Hope — Alt. 209 feet (63 • 6 m.) . Looking direct- 



ion 7 km. ly down the valley from Yale, a high mountain 

 fills the view and at the base of this is the town 

 of Hope, from which point the old Dewdney 

 pack-trail, once the main highway to the 

 interior of the Province, runs eastward over 

 the mountain ranges. The Paleozoic rocks 

 are again in evidence at Hope, and on them 

 rest patches of Cretaceous conglomerate, 

 remnants of a larger synclinal basin which 

 once stretched southward, across the Inter- 

 national Boundary line. 



75 m. Ruby Creek — Alt. 96 feet (29-3 m.). Half 



120-7 km. a m il e beyond Hope, a younger massive 

 hornblende granite appears, and from here 

 down to Agassiz at the head of the delta of the 

 Fraser, this is the prevailing rock, though occa- 

 sionally as at Ruby creek one sees exposures 

 of the Carboniferous rocks. 



"The relationship of the later hornblende 

 granites to these sediments is particularly well 

 shown. Where the unroofing of the granite is 

 rather far advanced, it appears as fairly regular 

 masses elongated in a northwesterly direction 

 and therefore cutting across the strike of the 

 sedimentary rocks. Beds are truncated sharply, 

 but appear again on their strike, across a 

 width of two or three miles of granite, quite as 

 if no interruption had taken place. Where un- 

 roofing is still imperfect, granite occupies the 

 lower slopes of the hills and is capped by the 

 bedded rocks. These receive numerous dykes 

 and sills from the granite beneath, but preserve 

 their strike and dip entirely intact. In short, 

 there is shown most convincing evidence of 

 replacement, rather than displacement, of the 

 sediments by the invading magma." (N. L.

Although the trend of the valley is now direct- 

 ly across the strike of the mountain axes, the
