[ Editor: from a 1994 alt.usage.english thread, "the Department of
Redundancy Department", in which "The La Brea Tar Pit", the "Great
Sahara Desert" and "Mount Fujiyama" had been offered: ]

> Just southeast of Boulder, Colorado, is a flat-topped hill called
> "Table Mesa".

And another: a village in Cumbria, UK, called "Torpenhow" [=
"Hillhillhill"].  I've read there's a Torpenhow Hill nearby, but that
may be apocryphal.

[ Editor: from a 1994 rec.puzzles thread on the most common city name,
where SPRINGFIELD had been proposed: ]

Common enough, but I bet it isn't the most common, (at least if you
include towns as well).  Then, in the various local languages, I bet
the winner by far and away is NEWTOWN !

Especially if you include variants such as Newton, Naples (Neapolis),
and even Carthage, which I've read is Phoenician for New Town.

This last one gives us a (probably not unique!) double barrelled
"NewNewTown", Carthago Nova, in Spain !  (Or do I mean Cartagena
Nueva... ?)
