This cursory article does raise one interesting question: Just how much conflation has there been between sightings of Bigfoot and the Wendigo of legend? The Wendigo has its own unique lore. According to Indian legend, when a human resorts to cannibalism to survive the brutal winters of the north woods, that person is cursed to become a Wendigo. Also, it is possible for humans to become possessed with the spirit of a Wendigo. Oftentimes these two pieces of lore are merged, and it is the act of cannibalism that leads to the person becoming possessed. Other times, the person is possessed and then turns to cannibalism. Which comes first? It depends on who is relaying the story.
Now suppose that there were sightings of Bigfoot/Sasquatch in the historical territories of the Native Americans from whose lore the Wendigo is born. It is only to be expected that there would have been. Would not a witness, upon sighting a Bigfoot, immediately think he had seen a Wendigo? Even if the two are completely different entities? Might not reported Wendigo sightings have actually been sightings of Bigfoot?
The linked article suggests that there are two kinds of Wendigo, one corporeal and the other a spirit. Because the matter was not confusing enough already.
