The crack continues below the steps. It looks like a RIDB is formed on the steps and then the crack continues Southward
(to the rim).
That is what it looks like. There are two cracks there. They split near the base of the pillar, both run down through the steps and the the righ hand on appears to run to the left at the bottom step rejoining withthe left hand crack. The they go on down. The piece of the die between them is shifting position creating the RIDB.
