I was in Greenland on an eclipse expedition in the fifties, landing at Narsarssuak AFB in the south. Very near some Viking ruins. The lack of trees (except for a few bushes) is striking to a resident of the temperate zone. I am surprised that Eric didn't know about the icecap, since we were able to hike to it with little trouble, and even took a (very short!) bath in an icy lake.
