Gauging Progress Photograph by Bernard Tourte
Caver Sergio García-Dils de la Vega calls out his depth to fellow team members above him. He holds an altimeter, which provides preliminary readings of the distance below the surface by measuring barometric pressure. García-Dils is living proof of the project's physical demands. He lost nearly a pound a day during his total of 20 days below ground.
