The Lore

The Slide-Rock Bolter is a lumberjack tall-tale creature from the mountains of Colorado. Described as an enormous whale-like animal that hooks its tail over a mountain peak and waits, mouth open, for prey to wander into the valley below. It then releases its grip and slides down the mountainside at tremendous speed, devouring everything in its path. The tale is believed to have originated among miners and loggers in the late 1800s.
