Jeff and I just returned from a side trip from Buenos Aires to Iguazu' Falls National Park on the border of Argentina, Brazil and near Paraguay. The falls. which are larger than Niagra, are located in the remains of a protected jungle and are absolutely awesome. It is possible to view the falls from above and below by walking on pristine trails in such a way that you feel you can see the end of the earth where they tumble into the abyss. The largest is even named "Devil's Throat". This sketch, which doesn't begin to capture their enormity, is of a pair of falls named "Dos Hombres".
