Miles and 

 Kilometres. 



1,001 m. Pocahontas — Altitude 3,282 ft. (1,000 m.). 



1,611 km. This station is opposite the Cretaceous portion 

 of the outer fault block mentioned above. 

 The Cretaceous beds, however, are not well 

 exposed. A conglomerate band is easily traced 

 on the opposite bank of the river, where it is 

 seen in the fold which traverses the coal field. 

 The coal seams here are above the conglomerate 

 band and are mined in the western trough at 

 this station. The mine entry is on the strike 

 of a lo-foot (3 m.) seam. 



1,027 m. Fitzhugh — Altitude 3,457 ft. (1,057 m.). The 



1,652 km. mountains between Rocky and Sn?ring rivers 

 are of the block type and are built of Devonian 

 and Carboniferous limestone. The line of 

 fault separating the younger ranges from a wide 

 block which has evidently suffered a much 

 greater upthrust, is passed before reaching 

 Fitzhugh, a new town on the site of an old 

 trading post established by the Northwest 

 Trading Company in 1881 but long since 

 abandoned. The throw of this fault is measured 

 in thousands of feet, since the highest beds 

 remaining in this block were beneath the lime- 

 stone of the outer ranges. The structure to 

 the west is somewhat similar to that at the 

 summit on the Kicking Hors2 pass to the south. 

 The valley of Miette river is denuded on the 

 line of a local sharp fold or break. 



1,044 m. Yellowhead — Altitude 3,724 ft. (1,135 m.). 



1,790 km. The rocks exposed along the Miette river 

 are a coarse quartzite and fine-grained conglomer- 

 ates, which have been in places squeezed out 

 to show schistose structure. Interbedded with' 

 these are greenish grey slates, and beneath, a 

 few small exposures show dark argillites and 

 thin-bedded calcareous sandstones. 



Yellowhead mountain to the north shows, 

 above the conglomerates and quartzites of the
