I see ZERO point in packing an animal out in the dark. Headlamps or not, unless your elk dies very near a MAIN and well maintained trail you are just asking for an injury which could end your season and your ability to pack the rest of the meat out. Get the animal quartered, get it laid out on logs/brush piles if you don't have a tree close by, or hang it as high as possible from the closest tree a ways away from the gut pile. Piss all around where all the meat is and leave your sweaty undershirt close to the meat and all the animals will hit the gut pile instead of the meat. Get back in there early the next morning when you have daylight to see any obstacles and pack your meat out safely and with less risk to your well being. I leave the tag in a hidden place on the animal so no one can come along and make my tag dissappear and claim my elk.
One benefit of packing at night is the flies and bees are not as annoying as during the day,,,
If I had only one trip and had to choose then I would start with the backstraps, tenderloins and rear quarters.
