These tents represent the first camp of its kind: a temporary facility used to house unaccompanied migrant children between the ages of 13 and 17. The tent camp wasn’t always here. It was set up in June at this facility, right on the U.S. side of the border with Mexico. No reporters have been inside. A bipartisan group of mayors who gathered at the facility were also denied access. But by looking at aerial imagery, this is what we found out: The small tent camp is located within a port of entry facility in Tornillo, Tex., which opened in 2014. The facility is surrounded by a barbed-wire fence. Beyond that are vast fields. The small town of Tornillo is four miles away. El Paso is 40 miles to the northwest. It’s not the first time migrants have been housed here. A temporary holding facility for families was set up here in November 2016 as seen on these satellite images. It was removed in April 2017. New tents first appeared on June 10 this year. There are now 32 tents total. One small tent holds 10 bunk beds — 18 of these tents are set up here to house up to 360 teenagers. Temperatures can reach over 100 degrees, so the tents are air-conditioned. There are mobile bathrooms, a food hall, a medical tent and other support structures. By June 20, a soccer field was set up. Otherwise, there’s not much for the detainees to do. It costs more than twice as much to care for children at temporary shelters like the one in Tornillo than at permanent shelters. But these makeshift facilities could become more common if a zero tolerance policy continues to be enforced at the border.
