Explanation: Part of Mars is defrosting. Around the South Pole of Mars, toward the end of every Martian summer, the warm weather causes a section of the vast carbon-dioxide ice cap to evaporate. Pits begin to appear and expand where the carbon dioxide dry ice sublimates directly into gas. These ice sheet pits may appear to be lined with gold, but the precise composition of the dust that highlights the pit walls actually remains unknown. The circular depressions toward the image center measure about 60 meters across. The HiRISE camera aboard the Mars-orbiting Mars Reconnaissance Orbiter captured the above image in late July. In the next few months, as Mars continues its journey around the Sun, colder seasons will prevail, and the thin air will turn chilly enough not only to stop the defrosting but once again freeze out more layers of solid carbon dioxide.

Global Warming on Mars........whoddah thunk
Looks like global warming on Mars too! Our emissions must be spreading there through space. They need to quickly get upwind from us if they are to survive!
We have gotten several very strange looking pictures from the Martian surface over the last couple of years but this one tops them all. It looks like some sort of Viennese ceramic.
HI RES version has distinctive footprint trails.
Possible location for Bigfoot/Yeti. Going through my database now of UFO sightings and appearance of Bigfoot(s){is it BigFEET for plural?} Yeti(s).
Contacting Above Top Secret website for coverup article.
I knew I was on to something!
Well, we can’t blame THAT on humans!
Very interesting. Oddly enough, it reminds me of a drop of pond water viewed through a high powered (300x or so) microscope.
Must be my biology background.
