It is a Spanish word used in the SouthWest US for forest along a river. No particular reason behind the name, just a unique and easily searchable choice.
"Basque is a language spoken in the Basque Country, a region that straddles the westernmost Pyrenees in adjacent parts of northern Spain and southwestern France. Linguistically, Basque is unrelated to the other languages of Europe and is a language isolate to any other known living language."
I didn't know about the forest meaning at all. (Maybe a subconscious influence, if you've ever heard any reference to Basque.)
