Colorado gold rush ghost town revisited
At the height of the Colorado gold rush, the city of Victor, high up in the Rocky Mountains, had a population of more than 18,000 people.
The gold and the prospectors are now long gone, but the town remains - along with a few hundred residents.
Photographers, Jonathan Anderson and Edwin Low have collaborated as Anderson and Low for twenty-five years. Their haunting photographs of Victor feature in a new book, "City of Mines".
Jonathan Anderson spoke to BBC World Update's Dan Damon about the project.
