Trivia Challenge #3

What world-famous site is always moving backward? Hint: it is not in Europe.

Is it related to a river?

Niagara Falls? (Or Yosimite Falls, Stanley Falls and any other falls for that matter!)

Dave wins...because the lip of any waterfall is always eroding upstream.

Wow, all those years of college finally pay off! So do I win a free trip to the waterfall of my choice? <BR> <BR>Here's a bonus question: Why is the erosion at Niagara Falls significantly reduced at night?

PS: Finally thought of a way to tie this back to the Europe forum!! <BR> <BR>The answer to my bonus question above is related to the reason why my day-tour guide referred to Ben Cruachan, Scotland as the "Hollow Mountain"

<BR>I don't know the answer to the Niagara question,(this _is_ the Europe forum after all!!!) but I guess it's something to do with dams or electricity generation, since the reason Ben Cruachan is the Hollow Mountain is because it houses a Hydro elelctric plant inside it

That's right. About half (perhaps more) of the Niagara River is diverted at night to supply hydroelectric power. And Ben Cruachan is used as a pumped-storage hydro plant. <BR> <BR>
