Monterey to Scottsdale Road Trip Guide: Coastal Descent

This route traces a unique geological seam where the Pacific Coastal fog meets the Sonoran Desert sun. The 872-mile journey from Monterey, CA to Scottsdale, AZ follows US-101 south to I-10 east, crossing the Tehachapi Mountains and the Mojave Desert before ascending into Arizona's high desert. A little-known fact: the San Andreas Fault runs parallel to much of US-101 near Monterey, visible as a subtle scar in the hills near Parkfield, the earthquake capital of the world.
