The 127 blocks, some as high as 9 feet (2.75 meters) tall, are spaced at regular intervals around the hill, like a crown 100 feet (30 meters) in diameter.

On the shortest day of the year — Dec. 21 — the shadow of one of the blocks disappears when the sun is directly above it.

Interesting find, but assigning celestial significance there seems like a bit of a stretch.

If you tossed 127 blocks of varying sizes randomly into a field, one of them would likely exhibit some coincidently interesting effect during a solstice.

And another point against this claim.

... the shadow of one of the blocks disappears when the sun is directly above it.

I am not a scientist ... but, doesn't the shadow of any object disappear when the sun is directly above it ... on any day of the year ?

Just wondering ...
