He said to me that pinwheels are very common in nature. One of the few things I was any good at in school was biology and pinwheels did not ring a bell. Go search yourself and there's not much there and certainly nothing that would have been seen in my opinion anyway a 1000 years or so ago when these these drawings were done in this part of the country.
Remember about clicking on the pictures twice to make them bigger each time for a real good look.
Here is another at the same place (McKee Springs) in Dinosaur National Monument. A bit different but a pinwheel none the less. The was a huge exhibit of petroglph pictures at the Anasazi Heritage Center including the figures above but not this one. No picture in that exhibit included another pinwheel and they were from all over.
What these do resemble very closely are these.
Just to the west lies the McConkie Ranch where the roundheads are found. Nowhere in that picture exhibit was there a roundhead anywhere close to these and there are three examples here one of which is very dramatic in my humble opinion which since no one knows for sure has as much merit as the big boys and more than some astronomers. A couple different vantage points for these.
This is the third.
It is these that I think are telling.
Exactly 23 miles.
To me this means whoever made the pinwheels saw that design some how in the heavens and drew what he saw. They looked through a telescope/got a ride or maybe it was a hologram but they drew what they saw for sure.
The same with the two roundheads with the one slit. These people in this case again drew what they saw. The fact these places are so close together is interesting as well. I have not seen roundheads like these anywhere else and if any one has please tell me about them.
