NASA Photos: 'Trees' On Mars?

Among other things, the internet has been going crazy this week over alleged photos of trees on Mars, found in recent NASA photo releases. But experts say the "trees" aren't really trees at all, not surprisingly.

The incredible images seem to show pockets of spruces springing up from dunes and hills on the rust-colored planet's surface, but unfortunately, the pix are really just an optical illusion. The "trees" are actually trails of dark basaltic sand debris and erupting dust clouds caused by landslides as dry ice.
