Washington Monument reopens after three years.


It’s a hollow obelisk 555 feet high made out of three different kinds of marble and 36,000 stone blocks.
When the earthquake struck, it whipsawed the obelisk, showering debris on the tourists climbing its vertiginous heights.... It required 2.7 miles of new sealant between stones, and 53 stainless steel “saddle anchors” to bolt in place slabs on the monument’s slanted pyramidion in case of another earthquake.

Your Say

"vertiginous"? Really?
*sigh* OK, whatever....
"Saddle" fasteners? Really?
What a great "new" idea for monuments expected to outlast the civilization that erected them.(at great treasury expense) Low carbon steel,right?
Saaaay...where were those "fasteners" cast/manufactured anyway?

"..it whipsawed the obelisk."
Who, exactly, is expected to envision the "whip saw" phenomenon these days?
The percentage of "modern" folks that have ever actually used a one, or two man buck saw, or hand rip, or crosscut saw for that matter, is,...?
And no, "Tiller man" has nothing to do with the guy at the back of the sailboat, or behind a horse drawn plow.

"...36,000 stone blocks..."

That is *veneer*, look at the corners, notice how thin the stone is?
This is the 3rd year in a row that I have been working on large scale stone architecture projects.
I know this stuff.
Current project: Illinois Dept of Transportation.
Last project: Lake Gage Residence, Phase III, with 400 tons of stone so far, 2 more phases to go.

Saddle anchors? Please.
At best this is misappropriation of terminology.
At worst it's a dumb ass talking about stuff they have no business talking about.

Wow, you guys know a lot of stuff. And me, just a lowly Diagnostic Electrician, retired at that.

What's this I read about Laus Deo on a plaque somewhere on the top of the monument?

Y'all know the Washington Monument is capped with a small pyramid cast in aluminum? At that point in time, aluminum was very valuable because of the difficult in refining. So much so as to be similar to gold and platinum today.
