Last week I was driving through Pennsylvania, crossing the state when I noticed something interesting and odd--many of the streams and rivers seem to end in -kill. Consider... the Fishkill River, the Schuylkill River and so on.
So I naturally started wondering--Why are PA rivers given names like that? Were there a succession of "kills" of various kinds of fish (a la "Fishkill"), or is it something else?
It's a good search problem. Not terribly hard, methinks, but an interesting one.
How would you solve this search problem? Why such odd names?
