There are wolverine throughout Northern Canada, but populations are very sparse. I have spent a good bit of time in Wolverine country, but never saw one. Would like to have seen the one that stole the backstraps off the one and only Dall ram that I'm ever likely to shoot. It was warm at the end of August in the mountain range along the border between the Yukon and NWT. I had sunk the deboned meat in plastic bags into the cold water of a glacier fed stream. No idea how that thief found the meat, but he got the best pieces. I found distinctive tooth marks in the empty plastic bag in the morning. I did enjoy the ribs hams and shoulders, but have always wondered since what sheep backstrap tastes like. Good I bet!
