Old counties
[change | change source]- Klamath County was formed in 1851 from the northern half of Trinity County. Part of the county's territory went to Del Norte County in 1857, and in 1874 the rest was split between Humboldt and Siskiyou counties.
- Pautah County was formed in 1852 out of land which, the state of California thought, was to be given to it by the United States Congress from land in what is now the state of Nevada. In 1859 when the cession never occurred, the California State Legislature did not make the county.
