The drive from Grass Valley, CA to Ellensburg, WA follows US-97 for much of its length, crossing the Cascade Range and the high desert of central Oregon.

The route transitions from the Sierra Nevada foothills to the volcanic Cascades and the high desert of the Columbia Plateau. Notable natural attractions include Mount Shasta, the Lava Beds National Monument near Tulelake, and the Deschutes River near Bend.

• Mount Shasta: This dormant volcano offers hiking, skiing, and spiritual significance. The town of Mount Shasta has crystal shops and meditation centers.
• Lava Beds National Monument: Located 30 miles east of US-97 via CA-139. Features over 700 caves, lava tube formations, and Native American rock art.

Safety considerations include wildlife crossings (deer and elk) at dawn and dusk, especially in Oregon. Sheep Rock and the tumbleweed-prone sections near Shaniko require reduced speed.
