The gallery has moved here, but I'm not sure how to navigate their file system to find the picture.

Are we even sure that it's a picture of Mars? Has anyone been able to verify it? According to Google it's a relatively old picture, some sites date back to 2009, predating the Mars Curiosity landing. How accurate are the colours? The land around the 'forest' looks incredibly bright, almost pure white. Maybe what looks like dark green isn't actually green at all.
I'm not saying there couldn't be forests on Mars, but this doesn't seem like solid evidence to me.
