Whilst documenting the landscape of the USA Mexico border for some years (see La Linea) it became a frequent occurance to come into contact with migrants on their journey north of the border.
For many this journey ends with apprehension by the US authorities and deportation back to Mexico.
Often exhausted, without money or possessions, these migrants are processed and transported to an official crossing and escorted to the other side. A few are offered modest help in the form of clothing and food by humanitarian charities.
These images were made from 2008 to the present day at the Mariposa crossing in Nogales, Mexico with the assistance of the No More Deaths charity.
