PHYSICAL DIVISIONS 



Newfoundland may be divided into upland and lowland. Examine the 

 map of Fig. 13.1. The upland over large areas has remarkably little relief, 

 and generally breaks off in steep slopes to the lowland. Most lowland 

 areas are on weak rocks, and a number of the steep slopes between up- 

 land and lowland are known to be fault-line scarps; others are thought to 

 I be. An article of Twenhofel and MacClintock (1940) discusses the physi- 

 ography of Newfoundland and is the basis for the following review. 



The highest part of the upland is the Long Range topographic feature 

 along the west margin of Newfoundland. It has been referred to as a 



Fig. 13.1. Physical divisions of Newfoundland. After A. K. Snelgrove, Newfoundland Geological 

 Survey. The horizontally ruled areas are upland and the unruled areas, lowland. Small num- 

 bered uplands are 1, Hare Bay serpentine hills; 2, Highlands of St. John; 3, Indian Head Range. 

 The lowlands take appropriate names such as West Coast Lowland; Grand Lake-White Bay basin; 

 Notre Dame Bay basin; Bay d' Espoir basin; Trinity Bay basin; and Conception Bay basin.
