The humanitarian group Water Station put out this barrel of water—one of 160 containers placed throughout the desert regions of the California-Mexico border, where it can reach 120°F or higher. Volunteers of all political stripes monitor these spots every two weeks from spring to fall, checking for activity and refilling the water.
'In 2009—as I became aware of an increase in the building of walls and surveillance towers and other government activities along the 1,954-mile-long U.S. border with Mexico—I began photographing in earnest. That’s also when I discovered that the original barrel was a water station placed by a humanitarian group to help prevent the dehydration and death of migrants crossing the border.'
Border Patrol agents drag tires—like these near Calexico, California—behind their trucks to smooth the terrain. The process is based on a Native American tracking technique called cutting for sign, used to reveal footprints and other evidence of passage.
