I knew this as Redwood Creek from the 1990s as the friends/schoolmate of my son who lived near the end of this (and it was always remote and I knew at the time that there were many Redwood Creek's as names of things, like roads, around the County at the time).

I don't know where it started, they spoke Korean, but still called it "at the end of the dirt road up Redwood Creek.  Living about 1 km away, I knew where this was, and as they said Redwood, I said Redwood.

If you are a local and say it is Boomer, I nod my head and say apparently, "you (or someone you know) live here."  So, Boomer it is.
