American Bestiary

Taxonomically classified in 1910 folklore as 'Macrocrossos', it is colloquially known as the 'mountain whale'.

Possessing a distinct cetacean physiology, it features an immense head, small eyes, and a massive mouth resembling a sculpin. Its specialized tail consists of a divided flipper equipped with enormous grab-hooks. It secretes a thin biological skid grease from the corners of its mouth to accelerate its movement.

Inhabited exclusively steep mountain country where slopes exceeded a 45-degree angle, particularly in southwestern Colorado.

An apex ambush predator, it anchors itself to mountain ridges using its tail hooks, waiting motionless for days. Upon sighting a tourist, it releases its hold, utilizing its drooled skid grease to toboggan down the slope, scooping up its victim and using its momentum to carry itself up the opposing slope.

Invented by early 20th-century American lumberjacks as a 'fearsome critter' tale to frighten newcomers. The myth served as a cultural metaphor for the extreme environmental devastation and economic instability inflicted upon the Colorado landscape by rapid, greedy mining and logging expansions.
