A mining accident began on 5 August 2010 with a cave-in at the San José copper–gold mine in the Atacama Desert, 45 kilometers (28 mi) north of the regional capital of Copiapó, in northern Chile. Thirty-three men were trapped 700 meters (2,300 ft) underground and 5 kilometers (3 mi) from the mine's entrance. They were rescued 69 days later.
