Like Mcseal said, on our trips we have not found enough dry wood that we ever had a fire. On the river we camped along caribou hunting we thought if we gathered everything we could, split it to get the dryish center, and started a fire we could have a 45 minute fire after 45 minutes of prep work. That hunt was in the tundra where the river had little timber along it.
Our moose hunt was in a swamp where we lived in chest waders, no easy fires there. I have watched a lot of videos where people hunted rivers with more timber. I could see a stove being useful there, but don't have personal experience with that. Best advice is probably to ask your transporter if there will be anything to burn. It would be great to be able to dry gear even if there wasn't enough for a fire every day. Alaska hunts don't always offer a lot of sun and wind to dry stuff out.
