It's not that the right and left halves switched on the ground.  It's the
angle that the photographs were taken from.  I think both of us did the
shift since from the angle of the photograph it made the most sense.

We've now seen two pretty convincing "reconstructions" of this erratic.  But
if I'm not mistaken, both of them put the right half on the left and vise
versa.  How did the two halves get moved to their current configuration if
the reconstructions reveal their original orientation?  I would find it much
easier to believe that the rock split in two after it was deposited by the
glacier, and took its  
current orientation primarily by settling of the ground underneath.   
In that case, the left one should stay on the left in those reconstructions.
