Thanks for the link...at least in this picture "it" looks to be closer to 30 meters across.

Now that I'm looking again at the first picture that Orion posted, and it doesn't look like a impact crater so much as it looks like a hole someone dug in the ground.

I know looks can deceive, but shouldn't there be a raised rim of some sort? The "crater" appears to be level with the surrounding terrain, which somehow doesn't seem "right".
