Largest Man made Hole

The largest man-made hole in the world (surpassed only by the Bingham Copper Mine, UT, USA) is a diamond mine located on the outskirts of Mirny, a small town in eastern Siberia. Begun in 1955, the pit is now 525 meters deep and 1.25 kilometers across. The massive 20-foot tall rock-hauling trucks that service the mine travel along a road that spirals down from the lip of the hole to its basin. Round-trip travel time: two hours. Airspace above the mine is off-limits to helicopters, after "a few accidents when they were 'sucked in' by downward air flow..."
