what is this?!

    what appears to be smoke coming out of cracks in the ground, perhaps there is volcanic activity underneath the surface.
    perhaps the ground there is soft and often merges together, but tears apart over time too.

    just a few ideas about what I can see in this image.

    Those are seasonal 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. The wind then blows the dust and dirt into those fans. We want you to mark these with the blotch and fan tool. You can learn more about what these features are here and here.
