The Nordvestfjord "bench"

I found another striking image of the bench on the north side of Nordvestfjord while going through my vast air photo collection.  It shows the feature with great clarity -- looking from NW towards SE.  In the far distance we can see Scoresbysund and Jameson Land.  

The bench is referred to as a relict planation feature -- and labelled as part of the LPS or lower planation surface by Bonow and Japsen.  If the dissected plateau edge coincides with the outcrop of a basaltic layer, we can argue for some geological control.  Bonow and Japsen argue that there is an erosion surface that passes beneath the basalt -- they refer to this as an "etchplain".   They claim thast the feature must have formed later than mid-Miocene..........

But the extent of ice moulding is also very striking.  All in all, this has to be a composite feature owing its origin to multiple changes of climate over a vast stretch of geological time.
