The source of this cool water is a spring above Fountain Street on the southeast slope of North Mountain. Happy Hollow Spring probably issues from Arkansas Novaculite. The water appears to be of recent vintage-perhaps less than a century in age. Prior to 1960 when it was privately owned, it was called the Magnesia Spring and a pitcherful cost 5 cents.
