Trying to find climate maps of South America from the end of the Pleistocene has been...challenging.
I've got the area of the map I want to work with, but the temperatures aren't quite right (current climate is too warm for the setting I want). Problem is, moving to a colder time period throws off the environment, and while that's...um...kind of fine, I'm not a climatologist or archaeo-geologist and trying to figure exactly how tundra turns into arid desert turns into grasslands (and vice versa) is painfully complex.
I'm on the verge of just faking it.
*sigh* But at least I'm happy with the geography. Finally.
