PLATE C VII. MOVEMENT CHASM ON THE GREAT 



ICE BARRIER. 



From a photograph by E. H. SHACKLETON (Sh. 182, ^-plate), Dec. 15, 1902; look- 

 ing S. along the chasm. (Map A.) 



This deep scar results from the movement of the Great Barrier ice-sheet 

 northwards along the coast. The floating Barrier-ice not only meets, but eventu- 

 ally absorbs the land-ice flowing eastward down Barne Inlet into it. Figs. 1 and 

 2, Plate CVI., illustrate the same feature. The chasm allows, and masks, the 

 movement due to tidal action, and so may be considered in part a tide-crack, 

 or line of constant rupture between the ice of the Floating Barrier and that which 

 is firmly attached to land along the shore.
