The broad, deep chasm of Washtucna Coulee cuts through the sagebrush flats of the Snake River plateau country, providing a wonderful exposé of the power of the Great Missoula Floods that carved Washington’s coulees after the last great Ice Age.
As spectacular as Washtucna Coulee is, the most majestic view of this route is found by peering down Devils Canyon. Here, you’ll witness the full splendor of the incredible geologic history of this region.
