The original word is actually carcague and was introduced by Rufus B. Sage in his Rocky Mountain Life, Thayer & Eldridge, Boston, 1859, p. 170. Described as a half-wolf, half-bear of prodigious size, it is clearly a carcajou, a.k.a. wolverine, Gulo gulo. The Carcagne is absent from real French Canadian folklore.
