I'm going to say that hiding tracks is at least partially instinctive. I catch myself doing it subconsciously .. stepping across trails rather than in them when I intersect them. I also notice that I will instinctively step behind a tree when a helicopter or airplane goes over somewhat low. I do not know why I do those things, I just do them. Once you notice a previously instinctive behavior, then you respond to it by either deliberately not doing it anymore or by deliberately taking it up a notch or two, but you don't truly ignore it: that which as been seen cannot return to being unseen.

The Google Earth image makes that little hollow look a lot more populated than the image that EB provides. Looks like a little creative editing.
Again, this show is just entertainment. It's fake reality, like the Blair Witch Project. Fiction portraying itself as reality for entertainment's sake. I will treat any piece of 'evidence' as just a made up plot device used to advance the story.
Honestly, I think that the only person with a Bigfoot themed show who tried to actually pursue evidence was Stroud. And he was unable to get the network to sign off on another season of Survivorman Bigfoot... probably because he didn't spice it up enough for the TV audience.
This is my perception. They like the power that being the people who get to define the dogma for others, to basically be both judge and jury if not executioner, gives them via those few letters after their names. Ironically, there's a saying that those who can, do, and those who can't, teach. Academic "scientists" may need a reminder.
