The finale returns to the host's boyhood campsite, once drowned under Iron Gate Reservoir, now freed as the dam and reservoir are gone and the host's granddaughter will see the fall salmon return there. It renders the series' verdict on how much of the damming was ignorance, indifference or greed, and ends on a forward question: if a river can heal in weeks, what is a river for?
The series' verdict on the ignorance-to-greed continuum is the host's considered judgment, offered for listeners to test rather than a proven finding. Where each dam or decision falls on that continuum is open to different weighing.
