Here is how I see “the historical Bigfoot,’ there wasn’t one. Green, Dahinden, and Sanderson tried to invoke a history for Bigfoot in typical Fortean fashion, by citing old newspaper reports and stories. These stories can be cataloged: “true” historical accounts such as the alleged “Siege of Mt. St. Helens” that really don’t match up with contemporary reports (3 toed, long pointy eared apes); stories of literal gorillas seen in American forests, most likely imagination or falsifications inspired by press stories of gorillas in Africa; overtly “fake news” of hairy men or ape-men, something local newspapers would publish to boost sales or entertain their readers; Indian accounts that were tall tales and/or representative of an animistic Native Culture; and the European fascination with the hairy man myth and stories of giants finding a home in the New World in campfire tales and later in spurious news reports. Such a collection of dubiously authenticated stories was employed by Green and allies to form a basis for historicity, to give the Sasquatch/Bigfoot story (which originated in the 1950s) a covering back story.
For me, the Bigfoot story as we know it has its origin in the pop culture of the 1950s. The Shipton photograph renewed world wide interest in the Yeti, fortunately coined as the mysterious Abominable Snowman. The Sasquatch/Bigfoot is nothing but the Yeti transplanted to the North American continent via romantic imagination (bipedal, cone head and all); that’s why early on it was often referred to as “America’s Abominable Snowman.” The contemporary myth of the Sasquatch/Bigfoot has two foster fathers: Ray Wallace and John Green. Wallace created Bigfoot as we know it with his hoaxed track-ways, giving it the appearance of something solid behind the stories, something holding real evidence, and moved it beyond the ephemeral. Green, converted to Bigfootville because of two Yeti-like recent reports by white men, and one Indian witness report mirroring First Nation lore, rushed to link the BC Yeti to the California tracks (such tracks had not yet appeared in Canada) and all it took then was a claimed “sighting” of a bipedal large ape (again, a Yeti trope) by two Wallace employees to set in motion the creation of a new American myth.
This is why I find the Death Valley Days episode interesting. Anything that has potential to help explain more fully what influenced the early days of the Bigfoot story ought be considered.
P.S. Patterson is all important too. But without Green and Wallace, there would be no Patterson because there would have been no Bigfoot.
