An odd Chinese riddle

It's not often I get involved with conspiracy theories, but this is an intruiging one. In short, an odd image has been found by this guy on Google Maps, sparking a debate about what the truth could be.

Click for biggability:

Poring over satellite images of China on the free Google Earth service, he came across a strange plot of land [linked above] - approximately 900 metres by 700 metres, about the size of six Sydney Cricket Grounds.

The land, which KenGrok said was landscape that had been modelled for military purposes, is situated near the town of Huangyangtan about 35 kilometres from Yinchuan, the capital of the autonomous region of Ningxia, in northern China.

It's interesting reading.
