The great circle airline route from Los Angeles to London passes over Hudson Bay (very icy on June 10, 2012), and southern Greenland. The photos below, taken from our flight to London at an altitude of 39,000 feet show the terrain near the southern coast of Greenland. The coastal area is not covered by the continental glacier of central Greenland. The sea, within a few miles of the coast contained hundreds of icebergs.
The first photo shows the general terrain of coastal Greenland. From 39,000 feet you can see the curvature of the earth, look at the horizon.
The next photo shows a small, snow-covered glacier near the center of the picture, along with a terminal moraine (pile of rocks) spilling into an estuary.
