Don't underestimate the need to get an animal that size broken down. A friend shot a raghorn bull one evening. It started raining. He field dressed it and we went up with packs in the morning. It had started to snow during the night and there was a couple of inches on the bull when we got there. When we started breaking it down, the meat was still hot to the touch in at the hip sockets. They retain a lot of heat due to both the insulation of the hide and the mass. Snow makes for great refrigeration. If there is pink snow or pink in the snow avoid it. It is caused by an algae that can be toxic, though is more common later in the winter. Some may survive to the next fall. Other colors can also indicate different algaes.
