The shape of the icebergs also depends on local conditions. At the moment of calfing, ice- 

 bergs can be divided into two classes: table-like (figure 45) and pyramidal (figure 46).

Figure 46. Pyramid iceberg. 



The first are characteristic of the antarctic, where the icebergs are formed mainly by cleav- 

 age from level ice arms or by separation from the main mass of the shelf ice. In the high latitudes 

 of the arctic, near Franz Joseph Land, for example, where the flow of the glaciers is slow and 

 where the glaciers are narrow and comparatively high, ordinarily icebergs of almost perfect cubic 

 form are found.
