We saw lots of lion tracks in a dry wash near Blanco, NM. The second photo shows a spot where they crossed a set of coyote tracks, making it easy to compare the sizes. I am confident about the tracks, but slightly less sure about the dropping pictured in the fourth photo. Lions sometime leave droppings in a prominent place on a path to mark territory, and these were definitely in the middle of a lion path. And unlike the coyote droppings nearby, they didn't show any evidence of juniper berries (a big part of the coyote diet in this area, at this time of year).
