Photographic daydreams.
The second largest man-made hole in the world (surpassed only by the  Bingham Copper Mine in Utah) is a diamond mine located on the outskirts  of Mirny, a small town in eastern Siberia.
Excavation on the pit  began in 1955, and today it is 1,722 feet (525 meters) deep, and 3,900  feet (1.25 kilometers) across. Stalin ordered construction of the mine  to satisfy the Soviet Union’s need for industrial-grade diamonds  following the war.
The harsh, frozen Siberian landscape made  working on the mine a difficult proposition at best. Jet engines were  turned on the unyielding permafrost in order to melt it; when that  failed, explosives were used. During its peak years of operation, the  Mirny mine produced over 10 million carats of diamonds annually, a good  percentage of which were gem-quality.
Although open pit mining has  ceased in the pit, mining work is continuing by underground methods.  The massive 20-foot (6 meter) tall rock-hauling trucks that service the  Mirny mine travel along a road that spirals down from the lip of the  hole to its basin. Airspace above the mine is off-limits to helicopters,  after “a few accidents when they were ‘sucked in’ by downward air  flow…”
