The Grateful Dead having long lived in Marin County, it’s quite possible that an image like this helped inspire the song of the same name.
… Almost ablaze still you don’t feel the heat
It takes all you got just to stay on the beat
You say it’s a livin’, we all gotta eat
But you’re here alone, there’s no one to compete
If Mercy’s a bus’ness, I wish it for you
More than just ashes when your dreams come true
Fire! Fire on the mountain …
