stone cold- well i don't know of any outfitters. whoever flys you out will need to have a big game transporters lic. then by law they can not assist in the hunt including picking spot to hunt, spot game or any aspect of the actual hunt they can provide transportation, food and camp. and spot to drop you off. only area i know of that you might be able to do that is the Ivashak river on the north slope but i don't know who is doing flights to the lake to drop people off and then as you get down river you would have to deal with other hunters using boats to access the river. a friend that was a guide there used to do drop offs but he was flying winter cargo flightsfew years ago in western AK and go into a white-out and is no longer with us. there is an airboat service that takes people and drops them off , might be able to take you up river and you float out at your leisure.
noatak river area would also be a spot to go.i have heard of alot of folks floating that for sheep , bear, moose and caribou.
i'm sure that there are outfits that provide that service i just don't know them. in 29 years in Alaska i have only done 3 fly in hunts. i thought ak raft rentals might do that and both the raft places can probably tell you who does. google search may also bring up some hits. check state of ak web page under occ. lic. then guides and it will have some listed for the area you are wanting to go to. they list them by game management unit. i have a few friends thatare guides. one has worked for a guy i beleive upeast ofKotzebue. he is appearently getting away from guiding and going to do drop offs i don't know if it will also be float trips. good moose and caribou area. i will check with a couple guys in know that fly and one has guided so they may have some ideas.....i get off tomorrow for 2 busy weeks of spring bear and bowfishing for pike i probably won't see him until i return...jog my memory with a PM if i don't get back to you..at 57 i get attacks of CRS so i might need to be reminded.
if you are bowhunting only i can give you an idea...not totally remote but most of the time you would never know it......or if you are a very skilled rafter there is another spot i could suggest. i would like to take my raft and do that tripif my skills were better and "boys" larger
