Burkina Faso inhabits a landlocked savanna cut by three principal rivers:
- Le Nakambe (formerly the White Volta)
- Le Nazinon (formerly the Red Volta)
- Le Mouhoun (formerly the Black Volta)
Much of Burkina Faso is very flat (average altitude is between 650 and 1,300 feet [200 and 400 meters] above sea level), but in the southwest there are rolling hills, waterfalls, and dense woodlands. The country’s second largest city, Bobo-Dioulasso, is perched atop a rocky cliff of the Falaise de Banfora, or Banfora Escarpment.
This is also traditionally the wettest part of the country, supporting rice fields and plantations of cashew nuts and sugar cane. (from www.oxfam.org.uk/coolplanet/ontheline/explore/journey/burkina/geography.htm)
