Named in 1922 after Cattaraugus County in western New York, presumably by some homesick developer. (The owners’ names on this street’s first tract map are illegible.) “Cattaraugus” itself is derived from the Seneca Iroquois language. It’s said to mean “bad-smelling banks”, referring to the rotten egg stink of hydrogen sulfide wafting off the banks of the Cattaraugus Creek. (Not that you asked, but the smell may come from barite minerals dissolving in the groundwater.)
