Is The Washington Monument Shrinking?

WASHINGTON (AP) — Government surveyors have determined a new height for the Washington Monument that’s nearly 10 inches shorter than what has been thought for more than 130 years, officials will announce Monday.

The new measurement puts the monument at 554 feet, 7 and eleven-thirty-seconds of an inch, as measured from the floor of the main entrance to the top. Ever since the stone obelisk was completed in 1884, however, the historic height has been recorded at 555 feet, 5 and 1/8 inches. It’s a number circulated for decades on tours of the capital and in civics classes about the monument honoring the nation’s first president.

So could this be a case of an incredible shrinking monument? Has it sunk into the ground more than previously thought? No, not even close, said the chief scientist at the National Geodetic Survey, which conducted the measurement with accuracy to within one millimeter.
