Hyampom Hog Bear (Ursus unimorsus amantiporcus) is a fearsome critter from the tales of North American lumberjacks. It described as small brown bear with a sharp nose and curly fur. It is also said to have voracious appetite for pork, at times taking whole chunks out of them while they squeal in pain. It is said to live in mouth of the Columbia River southward to the Klamath.
While examining timber on a tributary of the Klamath River, California, Mr. Eugene S. Bruce of the Forest Services captured a cub hog bear, which he presented to the National Zoo in Washington. Its development was said to be watched with interest and its disposition studied by members of the Biological Survey.
Unlike many other fearsome critters, this creature was based off of personal experiences. The Mr. Eugene S. Bruce's account is also recorded in The Land We Live In, The Book of Conservation by Overton W. Price. In this version Bruce did in fact catch a cub with his bare hands while trekking through the California mountains; however the animal pictured is presumably not a hog bear.
