Keystone State county (4)

Ross

I believe the answer is:

erie

'keystone state county' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for erie that I've seen before include "Great lake in Eire" , "Spooky-sounding" , "Buffalo's lake" , "Superior companion" , "N. American lake" .)

I've seen this clue in The Wall Street Journal.
