 DETAILED DESCRIPTION 



LEVIS: THE SHALES AND CONGLOMERATES OF THE L^VIS 

 AND SILLERY FORMATIONS.* 



The high bluff on the south side of Main street, L6vis, 

 which runs in a southwest direction from the neighbourhood 

 of the Intercolonial Railway station, is composed of shale, 

 limestone and limestone conglomerate of the Levis forma- 

 tion. The Levis formation continues until the turn at 

 Point Levi is reached, and beyond that point one sees 

 only red and green shale and sandstone of the Sillery. 



Along the roadside at Hadlow, there is a cutting in one 

 of the sandstone beds of the Sillery. At this point the 

 sandstone is so folded upon itself as to give the impression 

 of considerable thickness. A few rods back, however, in 

 a ravine which cuts across the cliff, the same sandstone 

 is seen to have a thickness of only about 10 feet (3 m.). 



A few rods farther to the southeast, just beyond the 

 ravine, the red and green shales of the Sillery formation 

 are exposed. 



From this general neighbourhood an uninterrupted view 

 is obtainable of the bluff on the northern or Quebec side 

 of the river. The structures and formations displayed 

 in this bluff are of great geological interest. The church 

 on the bluff up the river and to the left is at 

 Sillery, the town which has given name to the formation. 

 The red colour of the bluffs at Sillery point can be seen, 

 and the red shale bluffs extend down to the wooded cove 

 which is almost opposite Hadlow. This wooded cove 

 was the landing place of Wolfe's army, and bears his name. 

 There is a fault at Wolfe's cove, and the cliffs from that 

 point to the citadel are composed of hard shales and lime- 

 stone of the Quebec City formation. The prominent 

 building across the river, on top of the bluff, is the city gaol. 

 To the left of the gaol are the Plains of Abraham, the 

 battle field of 1759. About half way between the goal and 

 the Citadel is the drill hall in the Cove Fields, and it was 

 the excavation for the foundations of the drill hall which 

 furnished the well-preserved graptolites from which the 

 Middle Trenton age of the Quebec City formation was 

 determined. The prominent cliff in line with this building
