Parabolic dunes and littoral zone


Note: The east and west halves of Bartolomé are connected by a narrow saddle. Prevailing winds have piled sand into a set of large parabolic dunes on the south (windward) side, while the north is dominated by salt-tolerant littoral zone vegetation and sports a narrow beach.
