You need to get rid of a lot of crap. 90lbs is too much. If you do a Fly in hunt in Alaska you are limited to 50lbs.
You better shoot for this as a Max. IMHO
Do I ditch the bear fence (8 pounds) as hike into the Absoroka Beartooth into grizzly habitat? I am on the fence on that but being solo seems would sleep better.
The bear spray?
The layers of clothes when will certainly be near single digits at time?
The tent (5 pounds)?
The sleeping pad, rocket burner (I know one guy that eats 100% cold food to save pack weight), cut down 3000 calories per day for 10 days?
I could make two hikes in to get camp set up but at 11 miles that would be 11 in with 45 pounds then 11 out at 20 (empty pack, bear spriay, rifle, gps, transponder and some water) then 11 in at 45. Two days for that strategy to get set up. When I get a goat, much less a black bear and/or wolf, then could be a lot of 50 pound pack outs from the 11 mile mark. 77 miles would not be unlikely.
I have done 110 pounds (all in weight including gun, water, binos but not clothes am wearing) for 9 miles in 50F to 70F and was not fun but made the hike at about 30 minutes a mile and blew through all my water by the 5 mile mark. Shredded my hamstrings for the rest of that archery elk hunt. Took one spill and gouged into my right shin on a rock along the trail at edge of ridgeline on a switchback.
I sorted gear this June at the vacation home and have not been back and won't until two days before begin driving for the hunts (WY pronghorn then on to MT goat). I have since bought a used down puffy and sleeping back which helped a bit on pack weight. I could skip 10 pounds of frozen, pre-cooked stews and pasta though that means even more Mountain Home salty meals. I could go with one pair of each sock (liner and wool) though as salt crystals build up in socks is like small razor blades and socks would not dry overnight in cold temps. I could ditch the compass and paper map. Toss out the Immodium and other meds in the First Aid Kit. Leave the spotter and tripod though from camp can glass portions of 4 mountain peaks if take the spotter.
I have looked at mountain hunt gear lists and once are at 5 days+ for a hunt in windy 10F - 40F range hunts in bear country then 50 pounds seems suicidal.
If had to cut weight then the bear fence, spotter and scope and some water is how would cut close to 20 pounds. Doable. After that point, not sure what to dump as weather can get below 0F and could dump snow for consecutive days so clothes and food are not easy to cull aggressively.
