Google and Bing have blurred/blocked something else
So with all this secrecy around you have to wonder what's under the green blur on Google that affects a part of Russia close to the Bering Straits. You can see the blur here :
So then we look at Bing and discover that it is also hidden here too but someone with more expertise in Photoshop has been copying and pasting not with getting heavy with the blur tool.
Have a look at the small lake closest to the pin and then look down and right you'll see where they've copied it from to do the cover up.
It's actually an old Russian missile complex but then that's hardly a secret anymore, and all what I've written above + pictures of the complex can be found here:
