You don’t have to be a native to shoot caribou like that. I know white guys who’ve done it, perfectly legal. Chip even had pics years back of him killing swimming caribou with a bayonet on a stick.

Nonresidents can hunt that area as well as many others up there. Anybody who wants to go probably should because last I heard the herds were in decline up in the brooks and western AK, probably not anytime really soon but there may come a time when it gets shut down for nonresident hunting.
