If you walk through the desert in southern Arizona you can find evidence of a major migration. Water bottles, shoes, food wrappers — these are some of the things left behind by the thousands of people who try to cross the border between Mexico and the United States every year.
For some people, the items are trash to be cleaned up; for others, they offer a window into a perilous voyage.
Combing The Desert
On a sunny day in February, De Leon parks his car and walks off a road north of Nogales, Ariz., into the cacti. He points out a blue backpack in the distance and a scrap of clothing on the ground. He says these are rest sites for migrants, places used to sleep, eat and change clothes.
"You know a lot of these sites are in the shade because people are trying to rest in the middle of the day and also try[ing] to hide," he says.
