Surrounded on three sides by mountain ranges, this is the eerie and desolate Dugway Proving Grounds, a large-scale biological and chemical agent testing grounds south of Salt Lake City, Utah. The US has tested all sorts of nasty things here over the last 65 years including flame throwers, chemical spray systems, biological warfare weapons and toxic agents.

Encompassing around 32 3200 km², there’s a large area of high-resolution imagery to the east which contains various empty structures including this spooky-looking thing.

Here’s some links for you: The Dugway Official Site, some ground level photos of the area and of course the obligatory Wikipedia page!

Thanks to Phillip Lockwood-Holmes and Matthew.

Here’s a neat trick - this is a satellite photo of the great lakes, the largest fresh water lakes in the world etc, etc.

Now if you click to the great lakes and them zoom in step-by-step you’ll arrive here:

which are the tiny-great lakes! Cool, huh?
