Picture of the Day - The Airliner Chronicles Part 11

I've been flying you all over glacial landscapes of Canada and Greenland the last couple of days, but for a brief change of pace, here's a bit of a geological mystery from the air. It's in North America, and if someone doesn't recognize it right away, and if no one tries to solve it, I'll toss in some clues later. There is an interesting story of geological assumptions and perceptions associated with this region. Have at it!
