Aerial view of same area shown in Photo One. From this perspective
it is obvious that these rocks have in fact been arranged into
large patterns. Archaeologists believe it was done by prehistoric
people, probably for agricultural purposes (see the Technical
Page of the newsletter for a more spectacular example of such
stone arrangements; Photo #3).
The pattern was simply too large to be detected by someone standing
on the ground. Compare the size of the trees in the ground and
aerial views to get a sense of the relative scales.
