The 26,000-Year Astronomical Monument Hidden in Plain Sight

On the western flank of the Hoover Dam stands a little-understood monument:

...commissioned by the US Bureau of Reclamation when construction of the dam began in 01931. The most noticeable parts of this corner of the dam, now known as Monument Plaza, are the massive winged bronze sculptures and central flagpole which are often photographed by visitors. The most amazing feature of this plaza, however, is under their feet as they take those pictures.

The plaza's terrazzo floor is actually a celestial map that marks the time of the dam's creation based on the 25,772-year axial precession of the earth.

    Hoover Dam is cooler than shit. Several years ago during a semi-temperate part of the year, I was in Vega$ for business (I don’t gamble, and didn’t have Penn&Teller tickets so business was the only thing that could get me to go there), an entire day of meetings got cancelled due to some stupid fuckage, so...I went to Hoover Dam. Took the tour, then wandered around that spectacular plaza and looked at all of the supercool shit. I’d love to go back and see what I missed.

    I'm with cthulhu. The Hoover Dam is the only thing to see if you visit Las Vegas. It is an Art Deco masterpiece from the age when dynamos and machines were wonderful, new and amazing. That Easter egg reminds us that engineers and hackers have been around since way before the invention of computers.
