    Yes, the dark splotches in the image you should mark down to the size of the blotch marker. Though these are craters.

    Those dark areas are blotches and fans which are deposits of dust and dirt. They are produced by carbon dioxide geysers on the South pole of Mars which lofts the dust on to the top of the carbon dioxide ice sheet in the summer and fall in the Southern hemisphere. We want you to mark these with the blotch and fan tool. You can learn more about what these features are here and here.

    Cheers,
