the horse tracks. The back one had a weird shoe if it was a shoe. You can see what we call the hoof's frog in the bottom center but I've never seen such a horseshoe track before. So I was thinking maybe it was a tennis shoe print coming toward me but it would be a very big foot... and I didn't see a matching print aligned with it appropriately. I saw these prints off and on for a lot of this part of the hike and couldn't discern what it was for sure.
