Not sure what's going on here Ash? I thought the McDonalds rumples were at the point where the ice shelf met the sea and started floating - suppose that's the "hinge zone" thinking about it. What's the significance of the rumples?

If i remember correctly,it is a rocky part of the sea bed which collects the ice shelf as it moves towards the sea.This in turn stops the brunt from calving off,hence the ridges in the shelf where the ice is being forced over and around the rock.This is the most stationary part of the ice shelf(and stable).
Due to lots of research by BAS they are predicting a "calving event soon"
hence the reason to build the halley 6 nearer to the plateu(actual continent).
No doubt some one will correct me if i am wrong(usually am).
