high arctic desert. Yes there's water, but no real vegetation.

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.
