THE MAXIMUM EXTENT OF PLEISTOCENE GLACIATION

1959) is discounted due to their abundance, to the lack of metamorphic 

 alteration rims and to the absence of such inclusions in the existing lavas 

 (Wheeler, pers. comm. 1960). Finally, in the Nain-Kiglapait area farther 

 south unequivocal erratics have been found within 20 m of the summit of

Man-O'War Peak which exceeds 1050 m and lies close to the outer coast. 

 Here erratics of garnetiferous gneiss rest upon anorthosite bedrock (J. P. 

 Johnson Jr., pers. comm. 1962). By extending this argument, it seems satis- 

 factory to interpret the Torngat blocks as true glacial erratics. 

 The evidence implies only that at some time during the Pleistocene the 



high summits were inundated by ice from the west. The work of Flint,
