Living Room Lecture: Geoglyphs of the Desert Southwest

Lecture from 10/8/2020 by Anne Morgan. The deserts of the American southwest contain one of the largest concentrations of geoglyphs outside of Peru’s Nazca Lines. These ancient Native American works of earthen art can be up to hundreds of feet long, and yet are often invisible until viewed from above. Before drones, GPS, or Google Maps, photographer Harry Casey began a unique archaeology project. Armed with nothing more than topographic maps, 35mm film cameras, and his beloved Piper J3 Cub aircraft, Casey spent thirty-five years documenting the region’s geoglyphs before natural erosion and human intervention could destroy these fragile sites. A newly published book, Geoglyphs of the Desert Southwest: Earthen Art as Viewed from Above, authored by Harry Casey and Anne Morgan, collects Casey’s photographs into the first visual record of these beautiful and mysterious features.
