    Check out the Google Earth satellite image, there’s a figure-eight, I wonder how it ended up looking like two craters side-by-side, their rims apparently touching.

    Here it is.

      The lower grey feature is the crater – the grey rock is impact melt breccia – the lava pool that flooded the crater after impact. The upper feature is erosional – river valleys – that only gives the illusion of a crater due to its roughly circular expression combined with the human eye wanting to see patterns. But the rocks there are definitively not crater rocks.
