Amazing shots! I've only really seen a pine marten once, and that for only a few moments, so to see these kinds of shots is SO much fun for me. Thanks so much for sharing!
What a find, Rik. Congratulations! And, to the forum member from WY as well. I've been going to the Park for 40+ years and I've only managed one sighting. The little rascal was scampering down a tree over in the Petrified Tree area. It came and went so fast that I never even got a shot. So I'm still watching and waiting.
