I've been following Sasquatch research for years. It is abundantly clear that the Sasquatches are real. They are widely dispersed over the planet, wherever there are wild, remote, mountainous, forested and/or impenetrable swampy regions. They are masters of bushcraft, very intelligent, highly telepathic, and extremely wary of Homo sapiens -- for which reason they avoid us 99.99% off the time and are rarely seen.
But there are exceptions to the rule, one of them being the so-called Patterson-Gimlin film of an adult, female Sasquatch that was taken in a backwoods, mountainous region of northern California in 1967. Here is a good analysis of the film and the huge, bipedal primate that appears in it, by Australian artist and researcher, Wayne Dowsent.
As a wildlife biologist, I have been studying the sasquatch (or bigfoot) for just over 50 years. For the past 25 years, the main subject of my wildlife research has been the scrutiny of evidence which appears to affirm the sasquatch as an existing mammal. During this period, I found this evidence to be not only compelling, but eventually conclusive in supporting the sasquatch as an existing North American mammal.

Meldrum has gotten a lot of flak from colleagues and critics over the years who take pot shots at his Sasquatch research, but then it has long been a truism that when you are drawing the most flak you are right over the target. Dr. Meldrum's research strongly points to the existence of a very large and hairy, extremely stealthy hominid living in the wilds of North America.
