Agree that night bulging can help locate elk. I suggest moving away from camp. However, where I backcountry camp, I am right among the elk. I regularly have elk around camp and hear them walking or vocalizing during any time of the night or day. I don't call from camp at night because I don't want elk coming in to camp at night. Sometimes they come by anyway. Hearing elk walk by the tent at night is a great thing.
