I agree with five trips. One for camp and weapon, one for cape and horns & three for the meat. The last couple years our alk hunting group has tagged between 9-11 elk per season. These were mature five pointers (not trophey heard bulls, but great bulls) spikes and a few large mature cows.
Only a couple were recovered with a rhino and the rest were all quartered, deboned and packed out. We have 5-8 freighter frames/Cabela outfitter frames that are on the mountian with us at all time. If the elk is more then a few hundred yard off the road, the hunter that bagged the elk quarters and debones the elk while the rest of the group finishes their morning hunt or can group up and enter the location on the Garmin Rhino GPS and at least three or more hunter come to the kill spot with pack frames. We load one hind quarter per frame, both fronts on another frame and have all the deboned meat placed in a meat bag weattach to each frame and either pack it out in the bag or strap it to a fourth frame (lighter load).
Nice to have a group of willing hunting partners to hunt with that know how to break an animal down, pitch in and help and willing to strap on a pack on for a few hundred yard to a couple miles. My favorite eleven day hunt of the year, even with it being the most physical.
