Sandhogs is an original portal to the unseen characters and systems of underground New York—revealing the essential “art form” of mining in the modernized city. Excavation of City Water Tunnel #3 began in 1970. For each mile tunneled, approximately one Sandhog has lost his life in a mining related accident. In 2003 Gina LeVay was granted rare access to photograph the “hogs,” in the tunnel and at off-site locations. Here are images from her newly released book, Sandhogs, published by Powerhouse.
