The photo below is a 400% enlargement of the top or northern section of the South City Area.  I refer to it as the downtown area since you will note a building which casts a shadow on the left side of the downtown area.  The shadow for this building reveals it to have three stories and a "T" shaped object on the very top of the building.  This area is the widest part of the south city downtown area and also appears to be in a bit of a depression.  The "stitching line" parallels the south city on its right side.
