Our final day on this remarkable river trip is based in Clarkston, at the confluence of the Snake and the Clearwater Rivers, near the heart of Nez Perce country. First thing in the morning, we boarded locally operated jetboats for a tour deep into Hells Canyon National Recreation Area. The tour went south into the narrowest and deepest part of the canyon, beyond the junction with the Salmon River, the “River of No Return,” which flows freely throughout its entire length, crossing the mountains of Idaho. Lunch was catered at Garden Creek Ranch, a remote oasis of orchards and greenery, right where Idaho, Oregon, and Washington meet. Upon return to National Geographic Quest, we were treated to two aspects of local history and culture: stories and music of the Nimiipuu, or the Nez Perce people, and insights into winemaking and wine tasting from Coco Umiker, owner and winemaker at the local estate vineyard, Clearwater Canyon.
