Re: The Final Days

Oops. Convincing. :-] My memory failure. Should likewise apply to anywhere 
far inland, such as large parts of Africa and probably central east Asia... 
and probably much of Antarctica.

Sounds good. But in a magnitude 13 earthquake mountains will produce lots of 
almost vertically flying debris, landslides and so on.

This should rather apply to dry regions behind a mountain range... but wait, 
I'm basing my thinking on the Alps (pretty wet on both sides, most weather 
coming from the west) rather than the Rocky Mountains... but then the latter 
were close to the Western Interior Seaway... hm.

On the contrary, I'd say, because rainfall reaches the sources and rivers 
faster there than elsewhere. Calcareous mountains should offer good 
protection against acid rain, however.

The most common recent literature date for their first fossils -- some 
central Asian pollen and *Archaefructus* -- is 124 Ma... "start of the 
Cretaceous" can't be far off.

Er -- all living broad-leaved trees except the ginkgo are angiosperms (as 
opposed to conifers, which like the ginkgo are gymnosperms [paraphyletic]), 
so angiosperm forests are nothing special... that wasn't your question, was 
it? (Or should I feel like saying bad things about the US school system...?)
