As early as the 1830s European settlers reported seeing a large, hairy biped roaming the Pacific northwest. Even before that Native-American legends told of a "Sasquatch" (meaning a "hairy giant") that lived in the region. However, no concrete evidence exists to suggest such an animal exists -- "concrete" here meaning tangible physical proof such as a body, or body part.
If a Bigfoot species did exist, it would seem likely that at some point one of them would die and leave a skeleton, or get run over by a car. But that apparently has never happened. What we have instead is a mountain of anecdotal evidence: eyewitness accounts, blurry photos, recordings of strange noises, and footprints. The problem with this anecdotal evidence is that much of it could have been faked. Even the most ardent Bigfoot believers admit that some of it was. Whatever wasn't deliberately faked might be chalked up to wishful thinking.
Below are a few of the more notable hoaxes (or suspected hoaxes) associated with Bigfoot.
