Well ... Dam!

 

Ah, Civil Hydro-Electric Engineering. As usual, no info on the slide, but using my magical searching powers, I reckon that his is Moyie Dam in Idaho.

In fact, this news article has a very similar shot.

Fort Randall Dam, July 1953

Yes, ANOTHER Fort Randall Dam slide.

Bonus 2 -

Big Scale Engineering

There's something satisfying about Civil Engineering on an epic scale.

Bonus -

The Golden Dam

Difficult to get a sense of scale with this slide, but I believe that that is a Damned huge Dam.

With a lovely golden sheen to it.

Bonus - Put your faith in the Lord and.... damn.

Perrsonally, I find massive scale civil engineering projects, like the building of the Fort Randall Dam, to be fascinating.

But even I find this slide rather dull.
