Here are a few of the highlight pictures from the month I just spent in Brazil and Argentina. Click to see larger versions: Ipanema beach. (Ipanema means "dangerous waters", incidentally.) Rio from the Corcovado (aka the famous Jesus statue.) Iguazu Falls. Yours truly in front of 700 megawatts at Itaipu Dam, the world's largest hydroelectric power plant. Caiman, Iguazu Falls. Lago Torres and Cerro Torres, Patagonia. Tiny human silhouettes before colossal wall of ice, Glacier Perito Moreno, Patagonia. Trekking across the glacier. Glacial blue. A bed of icy spikes. Sunset over Argentina. Full set here .
