HiUcrest station. At this station 

 193-0 m. Hillcrest a short spur turns off to the south 

 310-6 km. to Hillcrest town and mine. The 



mine is located on the western limb of a broad 

 undulating syncline on the eastern limb of which 

 the Bellevue mine is situated. Three seams, 

 14 ft. (4 -2 m.), 8 ft. (2-4 m.), and 9 ft. (2-7 m.) 

 in thickness, have been developed at this point 

 From Hillcrest station to near Frank the 

 Dakota rocks continue, the railway running 

 diagonally across the above mentioned syncline. 

 A short distance west of Hillcrest station the 

 immense Turtle Mountain rock slide is entered. 

 The great gash in the face of Turtle mountain 

 on the south side of the track can be well seen 

 from Hillcrest station. The slide took place 

 early in the morning of April 29, 1903, 

 and besides wiping out the surface works of 

 the Frank mine and imprisoning some 19 

 miners, demolished a number of houses in the 

 town of Frank. The total loss of life has never 

 been definitely known, but it is believed to have 

 been in the neighbourhood of 70. Two special 

 reports have been written on the subject of 

 this slide, the first by Messrs. McConnell and 

 Brock in 1903 [3], and the second in 191 1, by a 

 commission appointed to investigate the 

 condition of the mountain at that time [7]. 

 The total area covered by slide material is 

 estimated to be about 1-03 square miles, with 

 an average thickness of 45 feet (13-7 m.). It 

 is estimated that about 90,000,000 tons of 

 rock were displaced. 



The limestone of the slide is now being utilized 

 in the manufacture of lime. 

 194-9 m. Frank — Just beyond the western edge of 

 313-7 km. the slide the town of Frank is entered. Here 

 the Kootenay rocks are again met with on the 

 western limb of the same syncline as that at 

 Hillcrest. The Kootenay beds here are nearly 

 vertical or in places slightly overturned so that 

 the dip is 85 degrees to the west. Turtle moun-
