99 Years Later... We Solved It

I kind of feel foolish.  I posited adolescent sasquatch pranksters.

It was a blend of left and right brain activity.
It's a matter of record that, in adolescence,  they prank more than Raymond Burr on the set of Perry Mason. That was totally left, or analytical brain power.

IYet I also had the intuitive notion, more of a feeling really, that they would engage over millennium in that manner because they realized it's the exact kind of thing Raymond  Burr would have done  if he were physically strong enough.

I even had a spontaneous colorful vision that came from my pineal gland and projected onto the interior of my forehead.

The iconic moving images were of two  
big-foots on the dry lake bed, each lifting a huge stone above their heads to test their strength.

Them they put them down and pushed them so as make the scrape marks. 

 Incredibly, they were both wearing very bright,. neon pink bathrobes as a salute to Rains Burr who was known to answer his home door in a pink robe in a the 1940s and 1950s.

So the pure feelings (clarirsentience) mixed with the stark visuals, (clairvoyance) are both classic examples of right brain operation; the Intuitive mind in action!
