there is a cluster of these huts in a perfect circle.
However, you can't see any of the others from each other.
in the center of them is some sort of ring of stones
inside this ring used to be a fire .. now its not been used in a very very long time.. and the oddest thing was
there was a huge anthill exactly in the center of this ring of stones.. the anthill was almost knee high
and im not exaggerating...it was huge.. and it was perfectly round at the bottom and a perfect cone shape.
it was one of the most amazing natural thing ive seen.
as far as the use of the huts.. my understanding was
the shamans used them for ceremony. probably pipe and smoke .. they didn't not appear tight enough for a sweat. .. usually sweats are made of animal skin and the door always faces east. these seemed to face the center of this circle... would be easier to tell from an aerial view.
