EVIDENCES OF RECENT ELEVA TION 3 I 



says that the}' are found at the following elevations above the 

 lake, 290, 220, 180, 150, 105, 90 and 60 feet; also, "Similar 

 raised beaches are found in favorable localities all along the 

 shore of Hudson Bay." In Mr. Tyrrell's' account of his first 

 expedition through the barren lands of northern Canada, he 

 mentions raised beaches in two localities, one at Doobaunt 

 Lake with an elevation of some 400 feet above sea level ; the 

 second at the mouth of Chesterfield Inlet and on the south side. 

 In Tyrrell's" second trip through these regions raised beaches 

 are mentioned near Ferguson Lake at an elevation of from 400 

 to 500 feet above sea level, and on the southwest side of 

 Churchill River in the region of Deer River with an elevation of 

 some 600 feet. 



Conclusions. — i. The evidence favoring recent elevation of 

 from certainly 270 to 300 feet above present sea level on the 

 lands along the south and southeast coast of Baffin Land has 

 been shown to be of the most conclusive character, and can be 

 briefly summed up under three general headings. 



a. In the form of raised beaches. 



b. Unlike surface conditions intimately associated with a dif- 

 ference in degree of weathering at a well-defined elevation. 



c. In the form of extinct life. The remains of several genera 

 and species of living shells were found to be in greater or less 

 degree directly associated with the beaches. 



Furthermore, that the conditions attending this upward 

 movement at least show that the rate of movement was not 

 alike for all the localities studied, but rather indicates that for 

 some the uplift was sudden and rapid, rising by jumps or strides, 

 while for others it was more uniformly slow and gradual. 



2. Conditions strongly favor a present movement on Big 

 Island and in Cumberland Sound. This is shown in beaches 

 found in a great number of the fiordic valleys, which are at 

 ])resent out of the reach of high tide by some five to ten feet, but 

 so recently formed that not a sign of vegetation has commenced
