Explorers Symposium earlier this summer at Headquarters. Scientists and conservationists affiliated with and supported by the Society presented their findings and explained their recent work.

Christina Conlee talked about her research at La Tiza, in southern Peru's Nasca region. I was intrigued by her fieldwork excavating tombs in the region (she recently uncovered
evidence of human sacrifice at the site) despite the fact that many having been ravaged by looters. As she spoke about the iconography of the grave goods they've discovered and its similarity with the mysterious geoglyphs etched into the region's Pampa Colorada desert, I wondered how an eager traveler might go about seeing the Nasca Lines firsthand and what that experience would be like.
First off, some background on the pre-Inca
Nasca Lines: The 1,500-plus geoglyphs were constructed by the Nazca culture (200 BC - AD 600), not aliens, some 2,000 years ago, and extend over 190 square miles. Though they're virtually indecipherable from the ground, from the air, a monkey, killer whale, hummingbird, condor, and pelican among flowers, trees, and geometric shapes are clearly visible. The lines were designated a
UNESCO World Heritage site in 1994. The region's arid climate preserved them all these years though they are threatened by the nearby Pan-American Highway. The big question is what are they: Are they sacred, ceremonial paths, maybe outdoor temples, or did they perhaps serve an astronomical or agricultural purpose? Do they indicate the location of underground rivers or irrigation canals? Are they the creations of hallucinating shamans paying homage to a cult of water and the god
Kon?
