and the snouts of the two glaciers (depositing huge piles of 

 debris), the deposits are very erratically arranged. Moreover, 

 the waters of the Hooker actually hit the side of the Mueller 

 Glacier, dip underneath for half a mile, and then reappear as 

 a sort of miniature maelstrom. I dwell on this because it 

 shows how difficult it may well be for geologists in the year 

 10,000 a.d. (when the ice has long vanished) to explain the 

 origin of the topography in such a region as Mount Cook. 

 Much the same difficulty has occurred time and again in 

 regions glaciated in comparatively late periods, such as in 

 England, U.S.A., and even in the Australian Alps. One of 

 the most promising features in Antarctic scientific work is the 

 light it is bound to throw on geological phenomena somewhat 

 like this, though on a much grander scale.
