In this Indus symbol, a marker stone is superimposed on a track. Therefore, it refers to a marked route.

Comments:
This is Mahadevan's sign number 253, which I have redrawn to better reflect the original.
It is interesting to note that this symbol appears on two disposable pottery cups (See H-690 A and H-1082 A) alongside three container symbols. The cups are sized at three standard units. Unfortunately, it is not possible to determine from the photographs whether there is a line on the cups that indicates when the standard measure has beeen reached, or whether the symbol merely indicates that the cup itself is a standard measure.
