Elk Pack-Out Tips: Load Order, Meat Care and the Proof-of-Sex Trap

You already know the arithmetic. A boned-out bull with the head runs close to 290 lb, and if you keep each load near 40% of your body weight, a solo pack-out is a four-trip job. We ran those numbers in Elk Pack-Out Math, so we won't run them again here.

This piece starts where the math stops. The pounds are fixed the moment the bull tips over. What isn't fixed is which load leaves first, what happens to the meat you can't carry yet, how the weight sits on your back for six miles, and one Colorado rule that catches experienced hunters who quarter a bull the way they always have. Colorado's second rifle season and Montana's general deer and elk season both open Saturday, Oct. 24, so this is the week to think it through.

1. The head stops counting the moment you cut it off

Colorado's regulation says no one may possess or transport a carcass or any portion of one unless evidence of sex remains naturally attached to it. For a bull, that can be the head and antlers, the testicles, the scrotum or the penis. The catch is in the word "attached": a head and antlers carried separately from the meat do not satisfy the rule. Once the carcass is in more than one piece, evidence only has to stay on one portion, and the requirement ends once the meat is processed, wrapped and frozen, or stored at your residence.

The practical fix is old-school and easy to forget when you're tired: leave the evidence on a hindquarter when you break the bull down. A lot of hunters then make that quarter part of the first load so meat sitting at the truck is never separated from it. Other western states write this rule differently, so read your state's version before the hunt, not on the mountain. If your situation doesn't fit the language cleanly, call the agency. A three-minute call beats arguing with a warden at the trailhead.

2. The first trip is not the first priority

The instinct after a kill is to get a load moving. With a bull, the better first move is to get every pound off the bone, bagged and hanging before anything leaves.

The reason is heat. Idaho Fish and Game's guidance is that elk-sized animals should be quartered, and that a large animal left with its hide on can spoil even in freezing temperatures. A University of Wyoming carcass study on mule deer, a much smaller animal, found the hide-on side of a carcass still averaged 45°F after 10 hours in a 38°F cooler, while the skinned side had already reached cooler temperature. The same bulletin's target is lean meat at 40°F or below within 24 hours. A bull holds far more heat than a deer, so the gap only gets worse.

Meat cools faster spread out and hanging than it does stacked in a pack. If the bull goes down at last light, the job that night is to skin, quarter, bone, bag and hang. Hauling can start in the morning.

3. Hang what stays behind like you won't see it for a day

On a four-trip pack-out, most of the bull spends a night or more in the field. Idaho Fish and Game's checklist for that meat is short and worth following to the letter:

• Keep it off the ground and in the shade. If the only spot gets afternoon sun, string a tarp in front of it.
• Keep it below 40°F, where bacterial growth slows down.
• Get the surface as dry as you can before it goes in bags. Wet meat spoils faster and weighs more on the way out.
• Don't let it freeze solid in the first 12 hours. Meat that freezes that quickly after the kill can turn tough.

In grizzly country, hang the meat well away from the gut pile and somewhere you can glass from a distance before you walk back in. Check the food-storage orders for your unit, too; they are not the same on every forest. Our piece on where grizzly management stands covers the bigger picture in Montana and Wyoming.

4. Pack the frame, not the bag

A 70 lb load packed badly carries like 90. The rules are simple, and nearly everyone breaks one of them when they're tired:

• Meat goes against the frame. If your pack has a load shelf between the frame and the bag, that's where the bagged meat rides. If it doesn't, the meat goes in the main bag tight to your back, with soft clothing packed around it so it can't shift.
• Heavy goes high and close. Weight that sits low or hangs off the back pulls you over backward on every step up.
• Hips first, then shoulders. Cinch the hip belt on top of your hip bones before you touch the shoulder straps, then snug the load lifters. If your shoulders are burning on the first mile, the hip belt isn't doing its job.
• Lift it sitting down. Strap into a loaded pack while sitting on a slope or log, roll to a knee and stand. Deadlifting 80 lb off the ground with your back bent is how hunts end early.

On the first trip your rifle or bow is also on your back. A dedicated gun or bow boot that rides low on the pack frees your hands for trekking poles, which do a lot of work on a loaded descent.

5. The empty legs are where you lose a day

A four-trip pack-out is also three walks back in with an empty pack. Those legs decide whether you finish in a day or two. Compress the empty pack so it doesn't flop, carry only water, a headlamp, a knife, a layer and whatever you need for the country you're in, and walk back on the same line you scouted out. The shortest route on the map is rarely the best loaded route, so mark the good one on your phone the first time through.

6. Know what has to come out, and what can cross a state line

Western states take waste seriously. Wyoming, for example, requires hunters to take all edible portions out of the field, including the quarters, backstraps and tenderloins, so leaving the work for later isn't an option. Read your state's wanton-waste language before you decide what's worth carrying.

Driving home across state lines adds a second rule. Many states restrict bringing in whole carcasses or certain parts from places where chronic wasting disease has been found, while boned-out meat is generally allowed. That is another reason to bone in the field. Our CWD by state breakdown covers what changed this season; check your home state's import rule before you load the cooler.

The pack we carry, and its limits

For a multi-day hunt with the pack-out built in, we carry the Forge Creek Expedition Pack. It's a 5,100-cubic-inch bag (listed as 85 liters), roughly the same class as the big expedition packs you see on elk and sheep hunts: room for a spike camp going in and a boned load coming out. It ships with a removable gun/bow boot, a rainfly with its own carry bag, ripstop and water-resistant accessory pouches, and a 2-liter hydration bladder. It's $319.99 in Olive and $329.99 in Strata.

What we haven't done: Venator has not field-tested this pack. The specs above come from the manufacturer's listing, which does not publish a load rating or empty weight, and the pack has no customer reviews yet. If those numbers decide your purchase, email us and we'll get them from the maker before you order.

If you'd rather have a more modular, purpose-built frame system, the Eberlestock Destroyer 63L ($399 to $429) is the step up, though only a handful are left. The Eberlestock Brooks 7000 ($269 to $299) is the other option at this size, also in short supply. You can see everything else in our hunting packs.

The kit: pack plus two knives

Boning a bull in the field goes faster with two blades: a stiff one for skinning and a curved one for working meat off the bone.

• Forge Creek Expedition Pack, Olive, $319.99
• Mora/Frosts Skinning Knife #7146, $34.99
• Mora/Frosts Curved Boning Knife, $27.99

That comes to $382.97. Bring your own game bags, paracord and a tarp. First-time customers can use WELCOME10 at checkout on eligible items.

A timing reality check

We ship in 3 to 5 business days. If you're leaving for the Oct. 24 openers in Colorado or Montana, don't count on a pack arriving in time. Colorado's third rifle season (Nov. 7 to 15) and fourth (Nov. 18 to 22) still leave room. For every state's dates in one place, see 2026-27 season dates by state, and if this is your first DIY bull, read The DIY Elk Reality in 2026 first.

Frequently asked questions

Does the head count as evidence of sex in Colorado if I pack it out separately?

No. Colorado's rule requires evidence of sex to stay naturally attached to the carcass or a portion of it. A head and antlers carried separately do not count. Once the carcass is in pieces, evidence only has to stay on one portion.

Should I start hauling right away or bone the whole bull first?

Get it all skinned, boned, bagged and hanging first. Meat cools faster hanging than packed, and a hide-on elk can spoil even in freezing weather, according to Idaho Fish and Game.

How cold does elk meat need to be?

Below 40°F, and the University of Wyoming's target is lean meat at 40°F or below within 24 hours. Avoid letting it freeze within the first 12 hours, which can make it tough.

Can I bring a whole elk carcass home across state lines?

Often not, if it comes from a state or unit where CWD has been found. Boned meat is usually allowed. Check your home state's import rules before you drive.
