Was reading another question involving the Lunokhod missions and then I stumbled across this wikipedia page which stated:
In mid-1968, at the facility KIP-10 or NIP-10 (КИП-10 or НИП-10)[3] in the secret village Shkolnoye (ru:Школьное (Крым) - closed town Simferopol-28), near Simferopol, a lunodrom (лунодром - moondrome) was built. It covered an area of one hectare (120 meters by 70 meters) and was very similar to some parts of the lunar surface. It was constructed using more than 3,000 cubic meters of soil, and included 54 craters up to 16 m in diameter and around about 160 rocks of various sizes.
The pictures in the linked flickr account show someone's recent vacation photos of an overgrown patch of land, like the following (note, this guy had a really cool vacation):

But I don't see any historical pictures of the area. I know the Soviets were pretty air-tight with secrecy though... Do any photos of the first lunar rover testing grounds exist other than what I've provided above? Preferably from during a test-- or before the plants took back over the area. I cannot seem to find anything like that.
I'm pretty interested in what the first "simulated lunar surface" looked like...
I have found pictures, but a lot of them are not from good websites and could be pictures of anything.
@OrganicMarble pointed out a Google Maps Location for the American equivalent. If you have information/historical photos about this lunadrom instead I would also accept that. He also provided the answer for this :)! I'd like remaining answers to provide results for the Russian equivalent.
