After crossing the Andes, the road met the South Atlantic, where the wrecked Desdemona rests on the shoreline near Cabo San Pablo -- one of many eerie reminders of the treacherous waters in the region. Here, 30-foot tides and sudden violent storms make rounding "The Horn" the most dangerous feat in nautical navigation. At this point, we are nearly 100 miles south of the Straits of Magellan. The peninsula barely visible on the horizon is Cabo San Diego, the pencil-point tip of the South American continent. From the spot where this photo was taken, we would drive nearly another hour on a dirt road along the South Atlantic coast to the 40,000-acre Estancia Maria Louisa and the Irigoyen Lodge.
