Have a ball the planning's some of the best part, and yep it's serious muskeg. Aerial scouting is a good idea before hand as their range is enormous, like they could be in Calgary or Red Deer type stuff, that's a slight exaggeration but paint's the picture. Noralta's about the only game in town for reasonable light fixed wing for spotting out of Fort Vermilion these days I believe.
Hope you don't mind I take a stretched out moment to encourage you guys to bring proper magnums for rifles, I'm sure you have this in mind already given you've guided up north. Best to forget all the "30-06 good for anything" stuff on here and haul along something like a .338 Win Mag, .300 Mag and 200gr at least. I've nary seen anything as tough as a well hit, but not perfectly hit, Bison, it could save you a very, very long follow up. And following them isn't the trouble, it's hauling it back from wherever he decides to go.
Definitely not a minimalist creature rifle selection wise no matter what anyone tries to tell you on the internet!

They're bigger than stuff in Africa that has a minimum of .375 H&H on it, and every bit as tough if they make their minds up to be and don't give up. Good hunting!
