Charles Darwin WHY TRAVEL IN DARWIN'S FOOTSTEPS?

Charles Darwin's theory of evolution—the multi- branched "tree of life"—was such a dazzling leap in the history of science that it tends to over- shadow the epic voyage of discovery that inspired it. In 1831, the H.M.S. Beagle, under the com- mand of Captain Robert Fitzroy, embarked from England to complete the survey and mapping of the South American coastline. No one guessed that Darwin, the callow 22-year old hired to be the expedition's naturalist, would be both a gifted, intensely curious observer of nature and an ex- traordinarily intuitive geologist. We now view the Beagle's five-year expedition as the most impor- tant scientific voyage of all time.

Committed to a life in science, Darwin spent the two decades following the Beagle's return to England immersed in his expedition journals and notebooks, studying his specimen collections, conducting experiments, and corresponding with fellow scientists. Darwin's Beagle narrative suggests that it was his geologic discoveries in Patagonia—the relationships between the fossil and living forms of both marine and terrestrial animals—that would prove pivotal in developing his theory of natural selection. The marine fossils he found in the high Andes, well inland from either coast, supported his growing belief in the Earth's great antiquity and that violent cataclys- mic upheaval occurred repeatedly. Darwin finally published On the Origin of Species in 1859—the now-famous book detailing the biological mecha- nisms responsible for the diversity of life on Earth, for variation within species, and for the geographical distribution of species and varieties. Darwin's theory of evolution was an unequivocal and science-based rebuttal of creationism—a stand that placed him squarely at the epicenter of Victorian scientific and religious debate, the reverberations of which continue to this day.

Charles Darwin was, in many ways, the first conservationist—believing that humans represent but one tiny twig on an enormous and luxuriantly branching tree of life. Desk-bound and ailing dur- ing his later years, it was his memories of Patago- nia that most sustained him.What would Darwin think of the challenges facing Patagonia today? Our first expedition traced Darwin's explorations along the Atlantic coastline of Patagonian Argentina and the fjords of Tierra del Fuego. Our In Darwin's Footsteps (Part II) begins along the Strait of Magellan and heads north to the high Andes and the Pacific coastline of Patagonian Chile, Chiloé Island, and the volcano country in Aconcagua's shadow.

IN DARWIN’S FOOTSTEPS (PART II):
CHILEAN PATAGONIA AND THE HIGH ANDES, INCLUDING TORRES DEL PAINE NATIONAL PARK, VOLCÁN OSORNO, CHILOE ISLAND, AND DARWIN’S CROSS - ANDEAN JOURNEY TO MENDOZA

December 2-19, 2011

We rejoin our intrepid explorers, Captain Fitzroy and Charles Darwin, as the H.M.S. Beagle leaves the Strait of Magellan and heads north along the fjord-etched coastline of Chilean Patagonia. The province of Magallanes is truly a land of extremes—immense glaciers, ice-choked fjords and turquoise-blue lakes, towering granite spires, snow-covered volcanoes, alpine grasslands, windswept steppes, emerald-green beech forests, and mist-drenched temperate rainforests. The region encompasses the realm of the Andean condor and is home to a fascinating bestiary of unusual species—-the guanaco, mouse opossum, Darwin’s rhea, austral parakeet, Chilean flamingo, blacknecked swan, and many others.

Flying south from Santiago to Puntas Arenas, located on the Strait of Magellan, we visit two historic sites—Puerto Hambre (Port Famine) and Fuerte Bulnes (Fort Bulnes). Port Famine was the ill-fated colony founded by Spanish conqueror Pedro Sarmiento de Gamboa in 1584 to prevent British pirates from crossing the Strait and attacking Spanish settlements along the Pacific coast. More than two centuries later, in 1843, Chile established Fuerte Bulnes, later replacing it with Punta Arenas-—finally securing claim to the Strait of Magellan. As Fitzroy and Darwin did in 1834, we’ visit the grave of Pringle Stokes, the Beagle’s captain during the first South American survey. In 1826, in the midst of surveying the western shores of Tierra del Fuego, Captain Stokes took his life when the hardships of his command became unendurable. On that first trip, Stokes’ subordinate officer, Robert Fitzroy, took over as the Beagle’s captain—-leading ultimately to Fitzroy’s command of the second survey expedition, the participation of Charles Darwin as the expedition’s naturalist, and the repatriation of the three Fuegian hostages taken to England as part of Fitzroy’s misguided desire to bring the "civilizing" influence of christianity to Tierra del Fuego.

We’ll visit Cueva del Milodón, where the fossil bones of giant ground sloths were recovered. Darwin’s fascination with giant Pleistocene-age mammals (megafauna) began early in the Beagle voyage, when he discovered fossil bones of at least nine extinct species in northern Argentina, including those of a slightly smaller sloth, Mylodon darwinii. We’ll spend several days exploring Torres del Paine National Park, regarded by many as the most dramatic mountain scenery in the world. From our base at Hosteria Lago Grey, with its view of the Grey Glacier and the ebony-capped Cuernos del Paine, we’ll hike and experience this wilderness landscape much as Darwin might have done. Torres del Paine is one of the best places to observe and photograph guanacos. We should see the season’s first baby guanacos (chulengos) as we explore Paine’s lush alpine highlands. Our visit coincides with the peak of the bloom, the luminescent reds of Chilean firebush and Magellanic fushia contributing to the firestorm of color we can expect. We’ll explore elegant, old-growth forests of southern beech, listening for the distinctive tapping of a giant Magellanic woodpecker or the arrival of a noisy flock of bronze-green austral parakeets. We’ll scan the swiftest rivers for torrent ducks, whitewater afficionados, and watch quiet back eddies for Andean ruddy ducks, flying steamerducks, or ashy-headed geese. In Torres del Paine’s secluded valleys, we may even catch a glimpse of a Patagonian gray fox or a rare huemul deer.

The snow-covered volcanoes of the Andes appear like islands in a cloud-capped sea as we fly north up the coast, to the bustling Pacific port city of Puerto Montt. The entire country of Chile forms part of the Pacific "Rim of Fire" and geologists have identified some 2,085 volcanoes, 55 of which are considered active. We’ll arrive in Puerto Montt with ample time to wander the city’s colorful harbor, watch fishing boats off-load their catch, and enjoy the famous seafood and craft markets at Angelmó. Traveling northeast to the Chilean Lake District-—volcano country—-we are reminded that Darwin watched from the Beagle’s decks as the night sky lit up with the spectacular, molten-red eruption of Fuji-like Volcán Osorno. Darwin later learned that hundreds of miles to the north, Volcán Aconcagua and Volcán Coseguina (which he guessed to be 2,700 miles north of Aconcagua) erupted violently on that same night and that the earthquake associated with the Coseguina eruption was felt 1,000 miles away. The coincidence of these eruptions inspired Darwin to theorize that certain volcanically active zones must be interconnected at depth. Our own explorations here will emphasize the scenic, geologic, and biological diversity that so intrigued Darwin during his visit-—the algae-green Río Petrohué and its lava-bench waterfalls, turquoise-hued Lago Llanquihue, the Valdivian temperate rainforest at Lahuen Ñadi National Park, and the magical landscapes along the lower slopes of Volcán Osorno. We’ll hike through a rainforest preserve dominated by alerce (Fitzroya cupressoides), a Chilean and Argentinian endemic evergreen related to the redwood and giant sequoia. Thickets of native bamboo (Chusquea) form a distinctive understory in these ancient forests, attracting unusual birds such the chucao tapaculo, huet-huet, and green-back firecrown.

Darwin was especially intrigued by his visit to the Chiloé archipelago—-where even the indigenous creation mythology originates in the fiery crucible of the island’s volcanoes. Chiloé’s Isla Grande, the second largest island in Latin America, is surrounded by several smaller groups of islands, many of which are joined at low tide. To reach Isla Grande, we take a ferry across Chuchao Channel, which separates mainland Chile from Chiloé. The archipelago and its people, the Chilotes, present a culturally distinct experience, with architectural styles, music, dance, and craft traditions clearly distinguishable from those of their fellow Chileans. Darwin noted that the geographic isolation of Chiloé had given rise to several unique plants and animals. We’ll sample many of Chiloé’s highlights, focusing on Parque Tepuhueico, where we’ll explore lush Valdivian rainforests in hopes of spotting a Darwin’s fox, tiny pudú deer, or one of the shy, tree-dwelling marsupials. The coastal dunes and rocky beaches provide opportunities to see colonies of both Magellanic and Humboldt penguins in close proximity, rock cormorants, kelp geese, sea lions, sea otters, and many other species.

Of Darwin’s many horseback expeditions into the South American backcountry, none were as geologically fruitful for him as his cross-Andean traverse from Santiago, Chile to Mendoza, Argentina—all within the mighty shadow of Volcán Aconcagua, South America’s highest peak. Though our journey won’t require ten mules to transport our provisions, we’ll see many of the places Darwin did as he crossed the great Cordillera—spectacular multi-hued ridges of volcanic and sedimentary strata, Volcán Tupungato, Puente del Incas (a natural bridge) and its associated hot springs, the wildflower-dotted puna (alpine) along Uspallata Pass, and the climber’s trail to Volcán Aconcagua—before dropping down into the world-famous vineyard country of beautiful Mendoza. We’ll celebrate another grand adventure In Darwin’s Footsteps with a glass of Malbec held high in Darwin’s honor!
