The area that is now known as Del Norte was and still is inhabited by the Yurok (Klamath River Indians) and Tolowa Nations of indigenous peoples. The first European American to explore this land was pioneer Jedediah Smith in the mid-19th century.

For him it was literally "Land's End" — where the American continent ended at the Pacific Ocean. In 1855 Congress authorized the building of a lighthouse at "the battery point" (a high tide island on the coast of Crescent City) which is still functioning as a historical landmark.
