I'd 1st say, what style of hunt are you going on? As LDBrown said, much will depend on if you are going DIY, guided, out of a lodge, horseback, walk in camping?? Then, not counting basics needed for high country hunting, how comfortable do you need to be?
Anything outside of what you actually take in your pack, will be for comfort IMO, the style of hunt will dictate what you may need. As far as pack needs, I started 30-35 years ago packed similar to Sneaky's list, everything but the walk-in cooler
Took less than 2 years and my pack was down to only the necessities to complete the "mission".
The pack load in many ways will also be dictated by the style of hunt. I have bud's that now use outfitters 99% of the time, they show up with rifle, ammo and clothing and a few incidentals like a knife or 2 and coolers, that is about it, but that is the furthest extreme from DIY.
Sneaky's list, is comfortable for him, his load to carry, so it works. Great list to give you an idea of things to think about and weigh against what you need for YOUR comfort level. There are a few things I think all big game hunters will have that are necessity when high country hunting, like field equipment to manage your animal after it is down. That can be basic if using and outfitter/guide, or could be extra if alone like I hunt most of the time.
What I think is needed just based on a lot of elk hunting, comfort.
Comfort is extremely important IMO, I have slept anywhere from bed of a truck, to a friends 2 million dollar log home, if you don't get the rest you need to hunt efficiently, even a 10# pack can be a burden. IMO the camp sets the tone for the hunt (I usually hunt all day, light to dark. I do find my self wimping out more now though). I will nap on the hunt if I want, so will usually stay in the field. I will usually take more than I need for base camp, for eons it was usually a good tent and more crap than I ever used, but I had it if I needed it. Sleeping gear has always been a key element for me, if it was an air mattress (when the wife came along), or several sleeping bags on the ground, cot, whatever worked.
I joke with Sneaky about his list, mostly his pack list, but in all reality, it is what he feels is comfortable and that is the main thing. A 10 mile hike with an 80# pack, will often make a fella re-access his "comfort" level
Rambling because I got up too early and bored, but a good idea to try. Pack a high country load of what you think you may hike with, then go on a stroll with that pack where you live. At the altitude you are, you will know real quick if you want to re-evaluate it. Add the high altitude and temps on an elk hunt and that load can feel greater.
I now have/use a camper, which for me is comfortable with my physical condition, but my pack load has remained the same for over 25 years. Will post it later today.
