According to the original map, that river on the east side doesn't flow out of the lake. The text indicates that those mountains are very steep on the east side, and no one from the Two Rivers (the area between those two eastern tributaries) had ever crossed from east to west. Later on, though, refugees began crossing west to east, which indicates to me that the western slopes are significantly gentler than the eastern.

In any case, yes, I am limited by the information presented in existing maps, which can be somewhat excused by the backstory that hundreds of powerful magic-wielders wrecked the world as they went terminally insane. Who knows what bizarre geographic results that would have? Personally, I've always found that long, narrow archipelago on the southern coast improbable. It's far too straight.

edit: Oh, hey, I just followed the link to that other map--that's the original painting by Mitchell that I just posted the closeup from, and it's the one I'm working from.
