Thanks. I like watching things like this.
Does make a mockery of everything.

One thing for me is all the small "mountain ranges."
Honestly, they look to me like the tailings piles of rock which are left over from mining, so hundreds of years later covered over with greenery, trees etc.
And on the sides of some ravines (which I think are the mined areas), you can sometimes see what could be the teeth/claw marks of big digger buckets,
I watch Gold Rush. You see the piles of left over rocks, you see the teeth marks on the sides of the mines. It all looks exactly like that to me, except on a much larger scale, hundreds of years ago.
