antiseptic, learn the local plants for extra food/medicine. dont rely on solar panels. water filter, get some "darn tough" brand wool socks they have a lifetime warentee, if you survive the trip. wool sweater and gortex base layer or gortex sock/boot liner. waterproof boots, rain gear, get water proofing spray, gun lube, sharpening stone, and a little carving knife and keep your mind busy. some good dry gloves you can still shoot with. you can pack heavy and maybe not use everything or pack light and be ingenuitive. take lard and salt and honey , stick to whole grains not white flour, a cheap light skillet will last a season and you can toss it later, cast iron is heavy and nonstick pans are a dime a dozen at salvation army and they clean up without using water.
take a camera and gps, a nice camera will hold more memories than any pack you can find.
oh Danner Powderhorn boots look like they would be great in alaska.
take some trade goods, chocolate or extra ammo candy, cough drops, anthing that might make you a new friend if you meet a stranger. ive seen the meanest cats turn nice when you can share a creature comfort or trade something of value for some advice.
good luck!
