A lot of place names in English speaking countries are just names of natural or man-made features, but the etymology isn’t obvious. Like Portsmouth or Waterford are pretty understandable, but -don, -den, -ton (valley, hill, farm) are all just things.

The Eyebrow’s pretty cool though. Japan’s also got some good ones, like Thousand Leaves, Oak (just oak), or (loosely translated) Noodle Hill. They like numbers too, like Eight Door or Lake Twelve. There’s even a Silent Hill, but it’s not too silent these days with almost 700,000 people there.
