I just got back from a British Columbia moose hunt.
They will kill a few 50 inch moose in Alberta but they also kill a lot of 30 to 36 inch moose also. Alberta will probably be an ATV, truck, walking hunt.
Northern BC will be horseback with cabins. BC can also be a mixed bag hunt for mountain goat, moose, elk and grizzly. This area of has point restrictions (has to be three points for brow tine or 10 points on one side) because of this there isn't going to be many moose taken less than 40 inches. I think the representative moose for this area would be 45 to 50 inches with the ocassional one going 50 some inches. But the BC hunt will cost more than Alberta, $9,000 to $10,000.
$10,000 would be low end for Alaska guided hunts.For that you would probably carry a pack, sleep on the ground and eat MREs and spam. The higher end hunts will be $14,000 to $18,000. The Yukon and Northwest Territories will be $15,000 to $18,000 also.
Of course Alaska Yukon moose are going to be 50 inches up. In the Alaska range they had to be 50 inches to be legal.
Which areas are the most successful? Probably the high end Canada or Alaska.
The hunting in British Columbia was slow this year, the weather was warm with 70 degree days. Some of the hunters had multiple tags and went home without an animal.
Good luck with your hunt.
