(first airdate: April 23, 2016) Created by Al Bergstein for Earth Day 2016, this one-hour radio documentary describes the life of a most extraordinary modern outdoorsman, who died in January at age 104. A pioneering mountain climber, mountain rescue founder, ceramics engineer, kayak pioneer, coastal geologist, and environmentalist, this program features interviews with people who knew him: Jim and Lou Whittaker (mentored by Wolf), George Yount (who flew and kayaked with Wolf), and Jim Johannessen (who worked with Wolf on his pioneering shoreline restorations).
