Christa Sadler on Explorer John Wesley Powell
Explorer John Wesley Powell was the first white man to float the Colorado River through the Grand Canyon over 100 years ago. He's featured in a new book by Christa Sadler. She spoke with KDNK's Amy Hadden Marsh last week. Sadler talks about her book in Aspen Wednesday at 6 PM at the Pitkin County Commissioners room and at the Third Street Center Thursday at 6 PM. Both events are free. You can listen to the entire conversation by clicking here.
