Glaciated terrain in Svalbard

Two nice satellite images from Svalbard.  The top one is from the NW of the island, and the lower one is from the N part.  The top image shows typical jagged upland terrain, with many knife-edged ridges and steep peaks -- the shadows of these peaks on the snow is what gives the terrain a ragged or jagged appearance.  Don't know what the geology is.......

The lower photo shows an area with more extensive snowfields and plateaux, and fewer jagged peaks.  More interesting for glaciologists, maybe, but not for mountaineers.
