 drift covered and outciops are rare. 



The valley of Battle river is eroded in the 

 shales and sandstones of the Edmonton series. 

 As Camrose is approached coal seams are again 

 in evidence, several of which underlie the 

 town. 



The country between Camrose and Tofield 

 is rolling and partly wooded. The coal seams 

 in this area are being mined in a small way, 

 where the overburden of drift is thin.

The area traversed by the railway between 

 Tofield and Parkgate is underlain by the rocks 

 of the Edmonton formation, with possibly a 

 band of overlying Paskapoo which extends north- 

 wards and may cross the railway between Jun- 

 kins and Leaman. Westwards, between Hinton 

 and Parkgate, Cretaceous rocks lower than the 

 Edmonton may be found to outcrop. Through- 

 out this whole belt the strata in the eastern 

 half are but slightly inclined to the west, 

 while in the western half they are practically 

 horizontal. 



The Edmonton formation consists of a series 

 of shales and sandstones, often merely clays and 

 sands, deposited during the period of brackish 

 water which succeeded the marine invasion of 

 the central part of the continent during early and 

 mid-Cretaceous times. The formation is very 

 rich in coal seams denoting periods of abundant 

 vegetation. The coal-bearing beds of the 

 Edmonton formation are exposed over an area 

 of 30,000 square miles.
