    Are we looking at ice or desert here? Are these lakes?. I would be grateful for any info, and feedback. Keep searching. 😃

    No liquid water involved out all. Mars is a strange and interesting place. Those dark 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 thawing 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.
