The geometries are *defined* to be 4326 but the coordinates are
meaningless in that SRID:

If these coordinates are 4326 then the first has a longitude of
3239.3462 degrees and a latitude of -1650.4789 degrees.  Where is
that?  Apparently these coordinates are really in some other SRID
and they're mis-labeled as being 4326, or perhaps they have some
other meaning altogether.  What's the source of these coordinates?
