The enormous 'Gran Coloso' iron ore mine which closed in 1910. Note the person dead centre of the photograph.	See map.
	The two people in this photograph show the sheer size of this mine, which became exhausted in 1919. The tunnels heading into the mountain are very short and the miners probably decided not to continue.	See map.
	The mature trees on top of the mine indicate the height of the excavation, done by pick and shovel. Up until 1910, the ore was carried down to the railway by mule train.	See map.
	Pilot tunnels in the rock.	See map.
	This mine has been suggested as an open air auditorium.	See map.
