Mars - Zooniverse

So the Zooniverse project I choose to work on was categorizing different features on Mar's surface.  For this I specifically looked for fans or blotches on the surface of Mars.  Here is some examples of what I did.

In these pictures you can see both fans (the cone shaped outlines) and the blobs (the oval shaped outlines.  According to Zooniverse's web page, the fans are created by sublimation of dry ice.  As the dry ice sublimates some of the gas is trapped underneath other ice till it explodes and particles go downwind.  The blobs are created when there is no wind.  This is fairly interesting because even though there is little atmosphere it means that there is still wind.  That is something I wouldn't have expected on Mars.  I classified 25 different images for this project.
