What I learned and experienced. We hunted the Malchatna herd back then which I understand is really down now.
At 80 lbs you can take the kitchen sink. Take good glass. My Swarovski 15x outperformed my moderate quality spotter and was way more comfortable to use. Take a tripod for the binocs. One spotter for the group should work if you want but make it a good one.
We lived in the hip boots. Crossing boggy tundra instead of trying to skirt it saves miles.
I took an 18 inch square blaze orange flag and zip ties and hooked it to the highest tree (maybe 15 foot tall) so I could find camp easily in a featureless tundra. That was before GPS existed. Reassuring peace of mind.
Read a book that was spot on worth reading. "Hunt Alaska Now" by Dennis W. Confer. Believe what he is saying.
Head net. Citrus acid and small spray bottle for spraying meat to keep flies off meat. Important.
Wet wipes, good headlamp and xtra batteries, top quality rainwear, anti diarrhea pills, motrin, tums, plenty of coffee, folding hand saw for cutting brush to make brush piles to air meat if no trees for hanging meat, para cord, lots of jerky, water filter, flag tape. Two 55 gallon garbage bags, small tarps. I'm old school so I like a topo map.
Tape a ballistic chart with wind drift to your stock for that long shot. Rangefinders are light.
Don't forget the positive attitude and grin.
