View Tom Dempsey's favorite photographs of Patagonia (Argentina and Chile).

View Tom Dempsey's favorite images of Argentina, in Patagonia, South America: See the stunning natural wonders of jagged Cerro Fitz Roy and huge Perito Moreno Glacier in The Glaciers National Park (Los Glaciares NP). Lenga (Nothofagus, or Southern Beech) leaves turn a beautiful color in late summer and fall, in Tierra del Fuego National Park, near Ushuaia, which is cruise ship terminal for Antarctica. Buenos Aires, "the Paris of the south," is the home of tango dance and music.

View Tom Dempsey's favorite images of Chile, in South America: See the towers of Torres del Paine National Park, Lago (Lake) Nordenskjold, and hikers near Grey Glacier. Visit Serrano Glacier via day trip or overnight stay at Hostaria Balmaceda. The pink copihue (Lapageria rosea) is Chile's national flower. Visit an endangered Monkey Puzzle (araucaria) tree forest in Nahuelbuta National Park. The Brown Pelican species lives on American coasts as far south as northern Chile (and the mouth of the Amazon River).

Visit Perito Moreno Glacier in Los Glaciares National Park as a day trip from El Calafate, in southwest Santa Cruz province, Argentina. Easy boardwalks give wide views of Moreno Glacier, an impressive wall of ice 200 feet high and 3 miles (5 km) wide flowing into Lake Argentina. The glacier flows up to 2300 feet thick and originates in the huge Hielo Sur (Southern Icefield) in the southern Andes mountains. For the past 90 years, its advancing has equaled melting (up to 2 meters per day, 700 meters per year), and the terminus has stayed at one location. Flowing ice periodically dams an arm of the lake which rises for a few years then breaks across the nose of the glacier as a crashing river (in March 2004 and 1991). In 2005 (photos), a narrow river flowed across the glacier face which calved large chunks of ice into the water with a loud crash several times per day. The foot of South America is known as Patagonia, a name derived from coastal giants, Patagão or Patagoni, who were reported by Magellan's 1520s voyage circumnavigating the world and were actually Tehuelche native people who averaged 25 cm (or 10 inches) taller than the Spaniards.

View Tom Dempsey's images of Mount Fitz Roy, Argentina, in Patagonia, South America: See a golden sunrise spotlighting Mount Fitz Roy, which rises abruptly on the border between Argentina and Chile in the Southern Patagonian Ice Field in the Andes mountains, near El Chaltén village, in Los Glaciares National Park, Argentina, South America. In 1877, explorer Perito Moreno named "Cerro Fitz Roy" for Robert FitzRoy (no space before the capital R) who, as captain of the HMS Beagle, had travelled up the Santa Cruz River in 1834 and charted much of the Patagonian coast. First climbed in 1952 by French alpinists Lionel Terray and Guido Magnone, Mount Fitz Roy has very fickle weather and is one of the world’s most challenging technical ascents. It is also called Cerro Chaltén, Cerro Fitz Roy, and Monte Fitz Roy (all with a space before the R). Chaltén comes from a Tehuelche (Aonikenk) word meaning "smoking mountain" (explained by frequent orographic clouds). Cerro is a Spanish word meaning hill. El Chaltén village was built in 1985 by Argentina to help secure the disputed border with Chile. The nearest airport is 220 km south in the larger town of El Calafate. Mount Fitz Roy is the basis for the Patagonia company’s clothing logo, after Yvon Chouinard's ascent and subsequent film in 1968.
