A time projection chamber was inserted into the dam in 1988
The Hoover Dam literally straddles and divides two time zones.
This huge sundial is surrounded by the 12 signs of the zodiac. This designer built a Universal Clock next to a source of natural energy, the Colorado River. Again, that doesn’t mean much to an ordinary person, but has significant meaning in the occult. Energy, good or bad is very important in mystery religions, this coupled with the knowledge that
Satan/Saturn is said to be the keeper of time, is really a big deal in the occult.
