Introduction: The Ancient Klamath Connection
The route from Eugene to Sonora follows the ancient Klamath peoples' seasonal trade corridor—later the Oregon-California Emigrant Trail—linking the Willamette Valley with the Sierra Nevada foothills. Modern travelers trace this same path along I-5 and CA-99, covering 540 miles in about 8.5 hours of pure driving. Yet the real journey demands detours into the Klamath Basin's volcanic landscapes, the rumored site of the Lost Cabin Mine near Yreka, and the ephemeral wildflower fields of Table Mountain north of Sonora.
