Hello all, new to the board so bare with me if this is old news. Recently I became aware of some photos taken by the Mars Global Surveyor, that showed Vegetation on Mars. Now being the Bad Astronomy follower that I am, I remain very skeptical that this is actually vegetation. It seems to me that this is some sort of geological formation. But I was wondering if someone has another explanation. Anyway here is a link to the site that I found it on.
