My first experience with big game (mule deer) retrieval was with my Dad when I was maybe 9. I was "hunting" with my BB gun
He got a deer and I remember watching him gut the deer. I learned how to do it in those few minutes it took him to do it. When you're anxious to learn, you learn! I carried out his rifle, a Win Model 54 carbine, 30-06 and my BB lever gun. He dragged the deer down a very steep slope through the aspens and spruce to a small creek. Finished washing out the inside of the carcass in the creek. Humped it up the opposite side maybe 1/2mi to a logging road where we could get to it with our 2 wheel drive pick up. Very few 4 wheel drive vehicles around then.
For deer I usually gutted then dragged or carried out. Remote areas or really heavy deer I would quarter and haul out on a pack frame. For elk, quarter, debone and pack out obviously. When quartering to pack out, I've done it both ways- guts in and guts out. If you take your time not hard to completely skin on the ground using the hide as a tarp- rolling side ot side. Usually ending up gutting the animal anyway at some point to retrieve the tender loins. I don't split the pelvis like some do. No need to really.
Of course Africa game field care and retrieval is a different ball game altogether
The one caveat to all this, at least for game big game in AK, is that there was so much meat waste in certain units in Alaska that a
bone-in reg was established in certain areas. So much for boning out a moose into 10 or so reasonable loads of
backpackable meat. A large bull moose bone-in hind quarter is one heavy load! Yikes. - sometimes rivaling a wet brown bear hide
The other thing in AK law which changed along the way and makes some sense for determining numbers of legal males if restricted to sex in a group harvest... it called for proof of sex having to remain attached to part of carcass during retrieval and head/horns/antlers can only be retrieved on last load out. Caribou-sized game bone-in is not much issue and the number of back packed trips to get one out for me was three round trips if really pressed and I was feeling spry but four was usually more reasonable. The heaviest pack I ever carried any distance was a wet brown bear hide- good gravy! 190-200 lbs is enough!
