W1: Viewpoint where creek begins; canyon descent starts here; good dayhiker goal.
DOZENOW1 576934 4703923 11

O: Zeno Canyon Falls, below Hicks Spring; GPS probably won't work here.
DOZENOO 576860 4705917 11

W2: The base of the correct side canyon to go up (the earlier side canyon is a blind one); as you see from this map, the routes back up to the Plateau get easier the longer you wait to climb out of Duncan Creek Canyon, and maybe that's the most sane way out...
