Where's this? I guessed Victoria Falls but apparently it's not. Need the info for a quiz.  |

Hmmm... it does look like African terrain at the top of the canyon, but at the same time, I wouldn't rule out South America. Not wet enough to be Iguazu Falls, though.

I'd dispute that it's not.
I'll get back to you.

So - look at this picture -  See the line of rocks at the bottom? Plus it's very rare you get a waterfall dropping into a canyon/cutting in the earth's surface like you do at Victoria Falls -  So, I'd say it is Victoria Falls, especially as I've been to them about ten times. |

Look at at the countryside in my first picture as well.

Mark's right, thanks. Now she says it could be Vic Falls.  I told her that's what I said in the first place... |

Just to confirm then -  |

So, the message to take from this is the following - ask us anything and between us we'll come up with the answer.

Yep, I believe so.
I only went there once and I stayed on the Zim side, didn't see this canyon I don't think.

I'm just thinking about the earthquake that may have caused that.

You made me think about that so I thought I'd look it up.
It seems that there wasn't an earthquake but - "The basalt plateau over which the Upper Zambezi flows has many large cracks filled with weaker sandstone."
The water is just following and wearing out the sandstone. Over time the falls themselves move depending on how much of the sandstone they've scoured out.
"the Second to Fifth and the Songwe Gorges each represents a past site of the falls at a time when they fell into one long straight chasm as they do now."
"The falls have already started cutting back the next major gorge,"

Yeah, I know that 99% of the time, all of those canyons are made by erosion, but that looks like such a sharp 'crack' -- the apocalyptic movies like 2012 are always showing the earth just opening up like that, right after the hero has driven over that section, although sometimes the rear wheels are left spinning in the void for a few moments.

Or he just manages to come to a stop with the front wheels hanging over?
Then impossibly reverses back out the way?

Absolutely. In 2012, I think that somebody even fell out of the back of the vehicle and was hanging on with one arm. But this was a very lucky family, because they got from Las Vegas to Tibet and even saved the little dog and survived even though the Himalayas were completely submerged by the tsunami. 4 billion other people were not so lucky.

And the selfish Russian boxer guy turned good at the end by saving his son.
Plus the plane that was flown into a skyscraper just as the building collapsed out of their way.
Yep, saw that one.

I thought it was quite an accurate interpretation of the apocalypse.
No?

Thanks Patrick but I think Mark has already nailed it.
