The world’s biggest hole is located in Russia.

The giant hole is actually a diamond mine in Eastern Siberia near the town Mirna. It is 525 meters deep and 1.25 km in the diameter. View all the photos here.

Some guys said that this is not the bigger hole and report the Utah’s Kennecott copper mine and the US President as bigger ones!

From my point of view the Russian hole it looks more like hole, while the Utah’s looks more like canyon and US President more like an asshole!
