In mid-March, about a week before I returned to the States, I took a bus over the Andes from Mendoza to Santiago, Chile, to meet up with Gus. Gus and I have a friendship that began through a backpacking adventure in 2006: we took a 4 day trip with another graduate student, Eric, around a sacred mountain in Tibet. Eric later wrote an article about the trip that was published on the Grist online environmental journal.
Because Gus has been working outside of Santiago for the past 3 years, he has been staring at a mighty mountain named El Plomo for just as long. El Plomo is a glacier-covered peak that can be seen from Santiago on clear days when the city isn't choking in its own smog. As luck would have it, Gus decided to summit El Plomo this year when I was just a short ride away. So, after hopping on a bus in Argentina, I made my way over the Andes to Chile where Gus and I promptly drove into the mountains in his borrowed Trooper to tackle El Plomo.
The peak of El Plomo is 5400m (17,716 ft), and a portion of the trek requires the use of crampons due to a large glacier that must be crossed. Years ago, El Plomo was frequently scaled by the Incas for religious purposes, and in 1954 a group of archaeologists discovered the mummified remains of an Inca child.
Our trek up El Plomo started on a Saturday. We hiked in 5 hours to base camp, which is situated at 4100m. Several groups had summited earlier in the day. After a restless sleep, we awoke on Sunday morning at 3:30am to make our way toward the summit. We finally reached the peak 8 hours later (with one unplanned detour), and with great luck, the Andes were clear, sunny, and absolutely stunning. We could see Aconcagua, the highest peak in the New World, on the Argentinean side of the border, and for miles and miles we could see the rugged, dry rock of this amazing landscape. We spent 30 peaceful minutes alone on the summit before heading back down. The mellow hike down took 4 hours, and when we reached base camp all but two other people had packed up and headed home. We had the whole camp to ourselves.
El Plomo was kind to us with warm weather and clear skies. The weather often turns cloudy and cold by mid-day, and several trekkers have died attempting the accent.
The follwoing are photos from our adventure.
The trail to base camp had us hiking along a beautiful mountain valley. El Plomo is the snow-capped peak in the background.

At 4620m there is a refuge called "Refugio Agostini" for those in need of a shelter.

My battle wounds. Okay, technically, I got these while trying to learn how to self-arrest before tackling the glacier. This took more than 4 weeks to heal.
