Archaeologists working on the Texas-Mexico border have documented more than 230 ancient Indigenous pictographs and narrative murals that could soon disappear due to natural and human causes. There is “an urgent need to expediently document as many sites as possible before they are lost forever”, says the archaeologist and artist Carolyn Boyd, who founded the Shumla Archaeological Research and Education Center, the non-profit organisation that oversees the Alexandria Project, a $3m initiative to locate and preserve the ancient rock art of the Rio Grande region, which is under threat from increased flooding, as well as drug cartel activity.
