There is a young man from my town that went up to Alaska last summer and got on as a general worker for a large outfit. He worked hard (and the work was though with long hours). A more senior position opened up and he's been invited to return in the spring for the "promotion". Down here in the lower 48 he could probably be a guide almost anywhere, but from what I understand Alaska is a whole different animal. I also recommend that you get your foot in the door as a lackey at the place you want to work, put your nose to the grindstone (smoking salmon, hauling gear, or some other thankless task) pay your dues and work for the opportunities to move up the food chain... Good luck Jack London!
