An outfoxing wolverine

Another excerpt from Nunaga:

Another time a smart wolverine had the best of us. Nasarlulik, another Eskimo called Qurvik and I had killed some caribou, but couldn't get all the meat in our canoe to take back to our post. We decided to cache what was left. We skinned them out and put them on the ground, and gathered up a great pile of rocks to cover the carcasses. After the carcasses were well covered, we took a tea-pail and scooped up water, sloshing it all over the cache. Each pail of water froze, binding the rocks like cement. We were making certain that no wolves would get our caribou before we could return for it ourselves. The cache was frozen solid.

When we eventually got back to pick up that meat, we discovered that a clever wolverine had found a way to outwit us. Unable to tear the frozen rocks away, the cunning beast had lain on top of one rock until its body heat had melted the ice around it; it then plucked the rock out and did the same thing with the next rock, until it was able to pull enough rocks away to get at the caribou.
