Johannesburg is filled with mine dumps left by the gold rush that began in 1886. Nearly 2 million people live on or near the 6 billion tons of earth in the city's bleached-white and yellow tailings. Photographer Jason Larkin explores these dumps and shows how they are integrated into the sprawling metropolis's landscape, as well as repurposed to extract further gold. His book on the project, Tales From The City of Gold, will be published by Kehrer in October.
