Mars Challange: Find an eroded (not filled with sediment or lava) impact scar that is flat like so many impact sites on earth. Why are there not so many visible flat impact scars on Mars? Of course one must take into account the accuracy or inaccuracy of the image data itself, the interpretation of topography of Mars surface. When a meteorite hits the Earth at a speed of around 200,000 miles an hour it "impacts" the ground besides making a huge crater. Over time much of the crater rim can erode away leaving behind a round, flattened impact scar on the Earth's surface. Try and find such a site on Mars.
I found this one at Nilosyrtis. It may be an old impact site where the crater rim has eroded away leaving a round scar partly covered with dunes.
