Marty’s photo of the day #2780: I’ll let a short excerpt from my second book, Endangered Edens: Exploring the Arctic National Wildlife Refuge, Costa Rica, the Everglades, and Puerto Rico, explain this shot from the a few miles south of the Arctic Ocean:

We watched with binoculars, as the fox zigzagged across the tundra, apparently hunting for rodents. She was headed our way—getting closer, and closer. Didn’t she see us? Soon she was right in front of us. We all froze as she loped by, cut across a shallow channel, and disappeared over a hill. At no time did she acknowledge our presence.
