About the elevation, according to some map I just saw, it's not that much. Maybe 11 meters. I live in Sao Luis and that place actually looks like it is cero meters above sea level. So, my guess is that the whole area along that coast is pretty low. Not sure what causes this cool combination of desert and sweet water lagoons, but it's lovely.
