The Pantanal Mountain Ranges
Although the Pantanal is basically flat, the surrounding uplands and some other formations in the plain itself have specific names:
Serras are the highest elevations, reaching up to 3,000 feet a.s.l.
Morros and Morros isolados, isolated, up to 450 feet a.s.l.
Cordilheiras are the most typical geological formations in the Pantanal. They are slight terrain elevations located between the baías, with mean elevations of about 2-3 m above the sea level. While they are normally dry, they are subject to inundation during exceptional floods. They serve as high areas for the location of cattle ranches, and as a refuge for livestock and wild fauna during extraordinary and exceptional floods.
