One of the most incredible waterfalls in Washington State. The Palouse River plunges over a wide semicircle of volcanic rock into an enormous pool almost 200 feet below. Dark basalt and dry sage-and-grass landscape contrast this immense natural spectacle. The State park also has grassy picnic areas and restroom facilities. Primitive trails lead to the top of the falls and down into the gorge below.
