Corbin — At Corbin a similar outlying remnant of the 

 coal-measures is being exploited by the Corbin Coal and 

 Coke Company. This company is operating two mines; 

 No. I being opened near the valley level by means of a 

 tunnel along the strike of the seam, while No. 2 mine is 

 situated nearly 1,000 feet (305 m.) above the floor of the 

 valley. The geological relationship of these two openings 

 has not as yet been worked out, and it is possible that the 

 same seam is represented at both places. At No. i mine 

 the seam is nearly vertical and varies greatly in size, from a 

 minimum thickness of 10 feet (3 m.) to a maximum of 

 nearly 250 feet (76-2 m.) ; this great difference may be due 

 to compressed monoclinal folding. At the upper mine the 

 coal has been stripped near the top of the hill, and shows 

 the coal in a synclinal basin about 370 feet (112-7 n^-) 

 in width; the thickness of the coal near the centre of the 

 syncline having been proved by drilling to be over 100 feet 

 (30-5 m.). 



The upper mine is reached from the valley b}^ means of a 

 switch-back railway and the coal is worked in open cuts 

 with a steam shovel. The output in 1910 from No. i 

 mine alone amounted to about 142,000 tons.

 Kilometres. 



216-3 m. McGillivray — McGillivray station is situated 

 348 - 1 km. near the eastern edge of the main Crowsnest 

 coal basin, the rocks having general westerly 

 dips. From the station to the junction of the 

 North Fork with the main Michel creek, where 

 the coal measures proper are entered, the 

 railway follows closely the strike of the Fernie 

 shales. 



The Crowsnest basin has a total length along 

 its major axis of about 35 miles (10-6 km.) 

 with a maximum width of 11 miles (3-3 km.), 

 and is estimated to cover an area of about 230 

 square miles (526 sq. km.). In a section 

 measured near Morrissey 22 coal seams, of one 

 foot (0-3 m.) and over in thickness, were noted, 

 containing in the aggregate 216 feet (65-8 m.) 

 of coal in a total thickness of measures of about 

 3.200 feet (975 m.). The greater part of the coal.
