Description: A large (20 to 35 pounds), dark-colored animal somewhat resembling a small bear in build. Total length 36 to 41 inches. Tail 7 to 9 inches. In coloration the wolverine shows variation, but with no sharp contrasts. The back is dark brown, shading to a paler color on top of the head. The sides of the body are marked with dull yellowish bands which begin at the shoulders and join near the root of the tail. The underparts are lighter and usually a “blaze” or spot of white decorates the front of the chest. The legs are short and exceptionally powerful, the large feet are armed with long, horn-colored claws. These register rather prominently in the track which otherwise is somewhat like that of a large bobcat. The breeding habits of the wolverine are not well known, but it is assumed the den is located among rocks in talus slopes. The average number of young is thought to be four or less. They are born early in the year.
This mammal, largest of the weasel family, possibly will never be seen by anyone who reads these lines, so scarce has it become in the United States. Yet, because it is such a notorious animal and so little understood, and because it has been recorded in both Utah and Colorado several times, and long suspected to have been a native of New Mexico, it is here included. It would be a shame, indeed, for a layman to see this celebrated creature and not be aware of this unusual good fortune.
The wolverine has been an object of fear and revulsion not only to the white man but to the Indian. It seems to be one of the few mammals which goes out of its way to create destruction and carries a chip on its shoulder toward all other animals which interfere with its desires. It is a creature of mystery, whose life history at this late date we shall probably never fully learn before it becomes extinct.
When the Hudson Bay Company trappers invaded upper North America they found the Objibwa Indians living in a sort of armed truce with the wolverine. They called it “Carcajou,” a term said to have been derived from the Algonquin, and accorded it the respect due a malevolent spirit. I have forgotten the Chippewa name for the animal, but I well remember that it was considered a “windigo” or evil spirit. Eskimos coveted its fur for trimming the hoods of their parkas. The long guard hairs protected the face from the bitter air without collecting frost, and the underfur did not collect snow and frost like other furs.

The scientific name of the wolverine is interesting. Gulo, the Latin term for throat, no doubt has reference to the gluttonous habits of the animal. Luscus, also Latin, means one-eyed or, as some authors suggest, blind. This may refer to the small eyes, so deeply set as to be almost invisible at a little distance, or may date back to the first wolverine taken to Europe from Hudson Bay. This specimen was said to have lost one eye, and the name may have been derived from that. At any rate, the normal wolverine is neither one-eyed nor blind.
The wide distribution of the wolverine provides an admirable example of what life zones mean. This same species lives at timberline in the high mountains of desert country and is also found at or near sea level far north of the Arctic Circle. It is well adapted to this environment, with exceptionally thick and heavy fur which does not mat easily with snow. In addition, during the season of greatest snowfall, the edges of the feet and toes grow stiff hairs which, in effect, act as small snowshoes, and enable the animal to travel with less effort.
Food habits of the wolverine are far from selective. Heavy and clumsy in build, it is doubtful if many large game animals fall prey to this awkward hunter. However, it does not hesitate to drive larger predators away from their kills and appropriate them for itself. At such times it eats as much as it can, then hides the rest for future repasts. It will return to the site until the remains are completely devoured, even if they spoil in the meantime. Natural prey includes rodents which it can dig out of burrows, and such ground-nesting birds as it comes across in its travels. It is said to be one of the few successful predators of the porcupine. Thief, predator, and scavenger, the wolverine roams its isolated ranges feared by hunter and hunted alike.
The wolverine is one of the few animals that seems to take malicious delight in harassing human beings. Though robbing of traps can be explained by hunger, theft and destruction of the traps themselves seems to represent deliberate and clever planning. So, too, does the breaking into and entering of isolated cabins with attendant pilferage of their contents. What cannot be eaten is either broken up and defiled or carried away and hidden.
