I am new to this forum, but have experience with caribou hunting in Quebec.I was there last Sept 1-6 with LUCO outfitters 130 miles north of Canapiscau. The first 3 days were hot- I hunted with only a thin shirt and blaze orange vest. It cooled then, and needed a fleece with a rain shell.Several thoughts:
1. If hot, there are millions of flies-you need to cover exposed meat with ground black pepper-2lbs should easily do 2 animals-and the meat should be kept in cheesecloth game bags. The flies are there in minutes after the meat is exposed.
2. That is the last week of catch and keep fishing- we actually planned 3 dinners of fish. The lake trout and specks are FANTASTIC eating!! Bring silver/blue and siver/gold 3"spoons and just longline them.
3. If you are going with other guys. one should bring a spotting scope- it was invaluable as you could spot the 'bous up to several miles away and plan a stalk. We used a Leupold 12-40X-I plan to get one for my next hunt as it is light and compact.
4. I took my gear to the bush camp in the largest of the BassPro camo packs-I used the frame to pack out half the caribou at a time(ie., 2 quarters)
5. Our weight was limited to 70 lbs, so you cannot take much. I took my Nokia knee-high felt linerrubber bootsreal coldrubber boots for hunting in, and a light pair of running shoes for around camp. I brought some over-boot warming liners in case I was onstand and it was cold-it gets very windy on those exposed hilltops. As it turns out, I stalked most of the time( I was hunting with a muzzleloader)
Hope this helps.
