Oh my - given a whiff of polar grid navigation, which allows a direction 
indicator once set to hold a chosen course, I see we are leaping to 
(totally unwarranted) conclusions about the Vostok Lake lying to the 
south west of the pole.
 Grid navigation specifies courses 0 to 359 degrees grid..... not often 
thought of as sou,sou-east, by east and all that good stuff....
And a polar projection does not constitute a polar grid for navigation 
in itself.....

But why am I burning electrons so fruitlessly?   :-)
