50 m. Tunnel — Alt. 3208 ft. (978 m.). The main 



80 km. ridge is tunnelled through near the western 

 contact of the Rossland alkali granitic intrusion 

 and that of the Nelson batholith. The tunnel 

 is about 0-4 miles (o-6 km.) in length. Its 

 east portal is marked by stratified clays. 

 Four miles (6-4 km.) south of the tunnel is 

 the Big Turtle filled by hydraulicking. 

 58 m. Farron — Alt. 3985 ft. (1214 m.). From 



93 km. about a mile (i -6 km.) southwest of the tunnel 

 to a point about three miles (4-8 km.) north 

 of Coryell, the railway traverses the granitic 

 rocks of the Nelson batholith. The cuts 

 show many inclusions of the igneous rocks 

 of the Rossland group and of crystalline lime- 

 stones. Southwards to the crossing of Kettle 

 river the rocks of the Rossland group are 

 almost continuously developed, associated with 

 minor intrusions of monzonite. The limestone 

 member is well developed in lens-like masses. 

 -]-] m. Fife — Alt. 1978 ft. (603 m.). Near Fife 



124 km, the limestone is quarried and shipped to 

 Trail smelter where it is used for flux. 



To the north and south of Fife an excellent 

 view is obtained of the trench occupied by 

 Christina lake (elevation 1450 ft. or 442 m.) 

 and Kettle river. From Kettle river crossing 

 to Grand Forks, the railway follows the river 

 valley, which is underlain by foliated rocks 

 tentatively referred to the Shuswap series. 

 95 m. Grand Forks — Alt. 1746 ft. (532 m.). Grand 



153 km. Forks [5] is situated at the junction of Kettle 

 river and its main tributary, the North Fork. 

 The valley is bordered by a series of terraces, 

 and the river meanders in broad curves through 

 the relatively wide bottom. 



The smelter of the Granby Consolidated 

 Smelting and Power Company is situated 

 on the North Fork about one mile (i-6 km.) 

 from the centre of the city. 

 109 m. Eholt — Alt. 3096 ft. (944 m.). From Grand 



175 km. Forks the railway follows the west side of the 

 valley of the North Fork and an excellent
