Lamar Valley, Yellowstone: This coyote and one of his buddies suddenly appeared in front of my moving car on a bridge. I was able to slowly drive alongside him and snap this. He looked sideways at me with a "get outta my face" look before he vanished into sagebrush beyond the bridge.
Stud Elk, Mammoth Hot Springs, Yellowstone: It was common at Yellowstone to see a giant bull elk, like the one above on the left, surrounded by a harem of females numbering as many as 30.
