Just before entering Stonewall a test pit may be seen 

 on the south side of the railway. On the north side, 

 spurs lead to the quarries of the Manitoba Quarry Com- 

 pany. 



Passing through the station, the track takes a semi- 

 circular course about the west side of the town, and turns 

 in an easterly direction along the north side of the quarry 

 operated by the Winnipeg Supply Company. In this 

 quarry, the deepest cutting has been made and the best 

 section is to be seen. 



The strata are only exposed in the quarries, being 

 elsewhere covered to a depth of 2 to 12 feet (.6 to 3.6 m.) 

 Below this the surface of the rock is generally deeply 

 scored, but in most cases the glacial polish has been removed, 

 in all probability by the solvent action of surface waters. 

 The rock is generally quarried to a depth of 12 or 14 feet 

 (3.6 or 4.2 m.) below the topmost bed. When quarried 

 it is used for crushed stone, rubble, and also for lime, for 

 which it is eminently suited. The floor of the quarry 

 is of red shale some 15 inches (38 cm.) in thickness, below 

 which is six feet (1.8 m) of limestone in two beds. This 

 is very hard, darker in colour than the limestone above, 

 and is unsuitable for lime. Below this is a dark red shale 

 which continues in depth below the level now exposed. 



The section in descending order is as follows: — 



Soil and non-assorted material. 

 Boulder clay or till of variable 

 depth. 



Stratified material. Alternate 



layers of sand and shale, one 

 inch to one quarter inch in thick- 

 ness. Shale is well assorted. 

 Sand layers are poorly assorted. 

 No fossils 16 inches, 41 cm. 



Boulder clay or till, lying on surface 

 of rock which is scored and stri- 

 ated 33 " 84 cm.
