Children's faces pressed against glass. Hundreds of young boys and girls covered with aluminium foil-like blankets next to chain-link fences. The pungent odour that comes with keeping dirty travellers in close quarters.
These were the sights from yesterday's tours of crowded Border Patrol stations in Texas and Arizona, where thousands of immigrants are being held before they are transferred to other shelters around the country.
It was the first time the media was given access to the facilities since President Barack Obama called the more than 47,000 unaccompanied children who have entered the country illegally this budget year an "urgent humanitarian situation."
Border Patrol stations like the one in Brownsville, Texas, and Nogales, Arizona, were not meant for long-term custody. Immigrants are supposed to wait there until they are processed and taken to detention centres. But the surge in children arriving without their parents has overwhelmed the US government.
The surge, which has been building for three years, comes amid a steep overall increase in immigrant arrests in southernmost Texas.
The children are mostly from Central America. They pose a particular challenge because the law requires Customs and Border Protection to transfer them to the Department of Health and Human Services within 72 hours.
That agency's network of some 100 shelters around the country has been over capacity for months and is now caring for more than 7,600 children.
Children began backing up in already overcrowded Border Patrol stations. Eventually, the Border Patrol began flying them to Arizona, where it set up a massive processing centre in the border city of Nogales.
Reporters in Arizona were also given a tour of the facility in Nogales. From there, they are sent to private shelters or temporary housing at barracks on military bases in California, Texas and Oklahoma.
But the children at Fort Brown remain in the custody of an agency ill-equipped to care for them. Yesterday, dozens of young boys were divided from dozens of young girls. Mothers with children still younger were in another cell.
Happier faces could be found in a side yard just outside the station. There, young children coloured pictures under a camouflage tent.
A group of about a dozen girls of perhaps 5 or 6 sat under another tent outside the shower trailer, dark hair wet and shiny. Women wearing blue gloves combed each girl's hair. Tables held stacks of clean bluejeans, T-shirts and toiletries.
