Just smell. I have come across quite a few dead animals just by being downwind of them even after just a day or so if the temperature is right.Wowza!😲 How did you stumble upon that beast? It looks like it is in really think cover.
Years ago on the deer hunt down in Indian Peaks we talked to a couple of other hunters who had been bow hunting there just a week before. They told us that they had arrowed a real nice bull but couldn't find it. The first day of the deer hunt we saw a lot of coyotes up in one draw coming and going. The next day all we would of had to of done was to follow our noses to find that elk. I called the bow hunters and told them where to look but I have no idea if them ever went into the draw to see if they could find the antlers.
