REPORT OF THE DIRECTOR igi2 93 



4 The land areas varied considerably in extent from time to time, 

 but the principal area of unsubmerged Precambric rock ran in a 

 northeast-southwest direction through the southern Adirondack re- 

 gion and most likely continued through the northern region. 



5 This prominent northeast-southwest structural belt or axis of 

 elevation, occupying practically the same position as the present 

 main axis of elevation of the mountains, has played an important 

 part in the geological history of northern New York.
