What ho! Geologists..............
Aren't there some amazing holes in this wonderful Earth of ours?..............For example:
1. South Africa
This is The Kimberley Big Hole - Apparently the largest ever hand-dug excavation in the world. This 1097-meter-deep mine yielded over three tons of diamonds before being closed. The resulting cavern was allowed to fill with natural water causing this amazing feature. It is currently stable in structure therefore local inhabitants can live along the edge of its opening without fear.
2. California
This is The Glory Hole - Monticello Dam, California - and it's the largest in the world of this type of spillway. Its size enables it to consume 14,400 cubic feet of water every second. A glory hole like this is used when a dam is at full capacity and surplus water needs to be drained from the reservoir. As long as no-one ventures too close when it is in use it poses no threat.
An amazing picture of The Great Blue Hole - This incredible geographical phenomenon is created by a circular coral atoll forming in the middle of the ocean. It is known as a blue hole and is situated 60 miles off the mainland of Belize . There are numerous blue holes around the world but none quite as stunning as this one. It poses no threat to humans.
4. Guatamala
This photo is of The Sinkhole that occurred February 2007 in Guatemala . As it formed - in a massive earth movement - it swallowed two dozen homes and killed at least three people. It is no longer believed to be a danger to the surrounding populace who still live in close proximity to this gaping giant.
5. England
This is the infamous 'Rat Hole of London' - It is reputed to contain 600 smaller A55 holes and together they are annually capable of swallowing Billions of pounds of Tax Payers Money. It is by far the most dangerous of all the holes featured here.....and shows no immediate sign of releasing its terrifying grip on innocent members of the public.
Tallyho!
