The route showcases three distinct natural landscapes. First, the Cascade Range: Snoqualmie Pass (elevation 3,022 ft) offers views of fir forests and creeks. In spring, wildflowers bloom; in winter, snow lingers. The Columbia River Gorge appears near Vantage, where the river cuts through basalt cliffs. Finally, the Palouse region near Moscow features rolling hills cultivated with wheat and lentils, especially photogenic in late summer.
