Christian Carollo is a time traveler.
Three years ago, the Philadelphia-based photographer found a box of his grandfather's travel photos with images of the Oregon coast, a place he'd be visiting the very next week.
"I wondered, what if I could replicate my grandfather's photos 30 years later?" he wrote on his blog.
As it turns out, he could. And Carollo hasn't stopped since. He travels the U.S. taking the same travel photos his grandparents took in the 1970s and '80s, everywhere from California's national parks to villages on the East Coast. He cross-references his grandfather's images with his grandmother's impeccably detailed travel journals to find the right spots. It's a labor of love that's fascinating to watch.
Of course, some places look incredibly different when Carollo visits them more than 30 years later. But surprisingly, many haven't changed one bit:
Carollo still has boxes of his grandparents' photos left to go: He hasn't finished the U.S. images, and there are international photos waiting to be catalogued. He has a trip planned for the fall, in which he'll make a dent in what's left.
Carollo's grandfather died since he began the Past Present Project. His grandmother says she's proud to watch him carry on the family's love of travel.
"She told me she's really happy with what I'm doing," Carollo told The Huffington Post. "That was awesome to hear."
