Morse code on Mars?

Strange photos showing a series of patterns that look like Morse Code etched onto the surface of Mars have spent conspiracy theorists into overdrive.A photo of the Hagal Dune field, below of Mars' north polar cap, appears to show a series of dots and dashes.But despite widespread hopes that the message might indicate an incoming close encounter, NASA dispelled it as a very familiar phenomenon. A NASA spokesperson said: "A circular depression (probably an old and infilled impact crater) has limited the amount of sand available for dune formation and influenced local winds. As a result, the dunes here form distinct dots and dashes."The 'dashes' are linear dunes formed by bi-directional winds, which are not traveling parallel to the dune. Instead, the combined effect of winds from two directions at right angles to the dunes, funnels material into a linear shape."The smaller 'dots' (called barchanoid dunes) occur where there is some interruption to the process forming those linear dunes."
