At one point in the late 1950's and early 1960's a carnival sideshow claimed a frozen young bigfoot creature. Crowds silently shuffled past the ice encrusted and frozen creature - forever caught in a twisted posture - as if warding off the demise that surely caught him.
Noted zoologists Ivan Saunderson was able - with assistants - to study the creature in the case. Detailed drawings, the best measurements capable in the setting and a photo or two were taken. He produced the first ever scientific study of an alleged creature. The findings were - unique - details were very specific for someone conducting a sideshow hoax. His conclusions , although tempered by the lack of real access to the remains (an autopsy or necropsy) and the questions the very existence of such a reality might present, did note that it laid open the path for his scientific fellows to consider the real possibility of an undiscovered hominid in the forests of the northwest.
As with all good stories - the ultimate end to this creature is clouded in mystery. It is known that the "real" or first frozen exhibit was replaced soon by a replica. A sideshow magic trick of staying one step ahead of legal steps regarding handling a dead body? The issue of a hoax being found out?
