Humboldt County’s first residents hailed from the Yurok, Karuk, Wiyot, Chilula, Whilkut and Hupa tribes, among others. They settled on the coast and along the banks of the Trinity and Klamath rivers. The county was created in May 1853 and derives its name from Humboldt Bay, which was “discovered” by a sea otter hunting party in 1806 and rediscovered in 1849. Douglas Ottinger and Hans Buhne entered the bay in 1850 and named it in honor of naturalist and explorer Baron Alexander von Humboldt.

Del Norte County has been home to the Yurok and Tolowa peoples for thousands of years. Legendary explorer Jedediah Smith is credited with being the first non-native to enter the region, in 1828. Gold strikes on the Klamath and Smith Rivers in the 1850s led to the settlement of the county, which was created in March 1857. Its name, meaning “the north,” is derived from its position in the northwest corner of the state.
