I recently received a copy of "The Scientist Looks at the Sasquatch II" from Joe Beelart . I have found the following from the Introduction and Commentary By Grover Krantz compelling and wanted to share it.
It has also been suggested that the sasquatch has some supernatural qualities that enable them to escape detection or elude pursuit. Obviously, no absolute statement should be made ruling out unknown abilities, but they exhibit no activities I am aware of that cannot easily be described in terms of quite normal animal behavior. Most big game hunters find nothing unusual in the ability of a large mammal to disappear where the cover might appear too meager or else impenetrable - it is the weekend hunter who has never tracked an elk who finds such things inexplicable.
Another common practice is for certain enthusiasts to repeat and embellish unverified accounts which then gradually grow into the truly fantastic. I have long ago stopped trying to make sense of them. Only if the event were witnessed by the person speaking to me, or some trusted friend of his, would I be at all concerned about unusual abilities. So far, the sasquatch appears to be a perfectly normal animal.
The totally unexpected and semihuman appearance of these animals constitutes a very effective built-in disguise. Many observers are reluctant to recount what they think they saw; others try to fit their experiences into a known framework and so alter them; still other accounts are invented or imagined for various reasons. For a researcher trying to wade through the consequent morass of contradictory and
incomplete data, it is a frustrating experience indeed. It is not so much the sasquatch which hides so well, but rather that people have inadvertently contributed to their concealment by their reactions to them.
