Iguacu Falls.


          The Iguazu Falls are
         located on the border
         of Brazil. They divide
        the river into the upper
           and lower Iguazu.
The waterfall system consists of 275 falls along
2.7 kilometres of the Iguazu River. Some of the
individual falls are up to 82 metres in height,
though the majority are about 64 metres. The
Devil's Throat, a U-shaped 150-metre-wide and
700-metre-long cliff, is the most impressive of all,
and marks the border between Argentina and
Brazil. Most of the falls are within Argentine
territory. About 900 metres of the 2.7-kilometre
length does not have water flowing over it. The
edge of the basalt cap recedes only 3 mm per
year.
