Settled? with a question mark just about sums it up. Great work by the team who did the revised dating, it definitely makes a stronger case for the 23kya age but as Davis points out they were measuring the layer below the footprints and then interpolating the age of the layer above. If someone can figure out a good way to test the actual layer the footprints are in then we can probably get to as settled a state as possible. Which in archeology, is never 100% settled anyway.
