So they are much smaller than the probable K/T crater.

Still pictures could be generated by Landsat, SPOT or some other remote
sensing service.  And the area may well have been photographed from
space at some point.  (Is Al Gore's plan to photo the whole planet
underway?)

Some large bolide craters are easily seen and have not been
substantially eroded.  They can't be considered 'convenient to reach',
though, as they're on the moon.
