ONLINE Geoglyphs of the Desert Southwest at ABDNHA
December 11, 2021 @ 6:30 pm
Across the deserts of the American Southwest are 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 Crosby began a unique archaeology project. Armed with topographic maps, 35mm film cameras, and his beloved Piper J3 Cub aircraft, Crosby spent 35 years documenting the region’s geoglyphs to capture on film before natural erosion and human intervention could destroy these fragile sites. Anne Morgan met Crosby while she was head Archivist for the Imperial Valley Desert Museum. In what began as an archival project of nearly 10,000 aerial images, progressed into a partnership as they worked together and co-authored the first ever book on these mysterious and little-known features.
