Searching for a photo project

Hey r/photography, I've been searching for a photo project that I came across online a while ago with no luck. It's probably been about 10 years since I saw this series. I'm hoping that someone else has run across it, and can point me in the right direction.

What I remember about the photo series: - Shot in the southwestern US, it focused on the shifting US/Mexico border, through a series of portraits & landscapes. - The portrait subjects were people who had lived in what was once Mexico, and then changed to the US during their lifetime (as in they didn't move, the borders did). - I believe the series was shot with large format film, but could be wrong.

Any help would be greatly appreciated, it's been driving me crazy for ages now.
