Henline Creek drains into the Little North Fork of the Santiam River, in the Elkhorn Valley. Henline Falls is the only waterfall which is accessible via an official trail. With the exception of "Henline Bridge Falls" (which are below the one-lane bridge on the unpaved road leading to the trailhead), all of the others are part of Family Falls, a set of unnamed/unmapped cascades discovered and named by Maynard Drawson and his friend Jerry Morey 30+ years ago.
