介绍：Asotin is the last city along the Snake River route to Hell’s Canyon, which is the deepest gorge on the American Continent. Hell’s Canyon is 5,500 feet deep at Dry Diggins. On your return from the canyon, a drop of 20 feet per river mile makes for fast water and shooting rapids. Etched into the canyon walls you can see the path that the Nez Perce Tribe took on their trek from their summer home in the Wallowa Mountains to their winter home in Asotin. Hieroglyphics, Bighorn sheep, elk, deer, black bear may also been seen along the banks and on the rugged rock outcroppings.
