Screw hole

Source/credit: esberat

This is not a screw hole in wood, but a giant sinkhole in Konya, Turkey.
The region has hundreds of sinkholes due to extreme droughts. 

Look close at the image below and see the people and cars to understand the scale of the image. A lack of context creates a forced perspective.
