I believe big bulls is right this bull is bedded down. While the ears are in what appears to be a alert position. The eyes are the dead give away they are relaxed with the eye lids drooping down a bit. Also you can see more of a round hump down the backline from the ribs pushing up. All that don't mean squat I guess.

60yds away you wouldn't see the relaxed eyes but you would see the alert ears posture. What I personally would do is use the terrain to my advantage if possible. If the terrain is working I would put out the decoy and mewwwww alittle on the cow call to see if I could get this bull up and moving in. If the bull started coming in I would try to slip down and around to the side to get a better shot angle. Most people know that hunt alone that bull comes into range it will most likely be a frontal shot only. You don't always have to stay in one place to call elk. My thing is to slip around the elk while he's slipping around you.

But my best choice on this particular bull would to be to take a good look at the trees and landmarks. Back off make a half circle around the bad boy and stick him while he's still on the ground relaxed. Every situation is different I've had many of bulls give me the slip too. Sometimes you out fox the fox.
