Thanks all for the positive reception

A little more info:
These images were made during a geological excursion in 2011 - led by the danish institute GEUS. Very professional people!
Needless to say we all had a blast. We encountered both musk ox, polar bear, hare, flying things, sail boat, and what have you. It is truly a magical part of the globe and the shear scale of things is breathtaking.
The images are all captured with a D3 and basically three lenses, the venerable 16/3.5 fisheye, the temperamental Ai-S 35/1.4 and the somewhat underdog one - 70-300/4.5-5.6 VR. The second and thirds pics were captured from our plane en route to our destination. More pictures to come.
