Klamath County might still exist today, had it not been for its geography. When Del Norte County was founded in 1857, Klamath was still a county, with Siskiyou to east, Del Norte on the north and Humboldt and Trinity Counties to the south.
The history of the northern counties of California goes back seven-years prior, when the state legislature created 27 counties. At that time the extreme most northern counties were portioned off into two counties, Trinity and Shasta.
A year later, Klamath County was carved from the northern part of Trinity and in 1852, Shasta County was divided, forming Siskiyou County. Then in 1853, Humboldt County was drawn out of parts of Trinity County.
At this time Klamath County entailed present day Del Norte County, parts of Humboldt and a chunk of Siskiyou. This, and the fact that transportation was poor, led to disagreements over where the county seat should be located.
At one point the seat was held in Trinity, later at Crescent City and finally at Orleans Bar on the Klamath. The Bar was a natural location because it was both centrally located and could be accessed by the river.
However during the early part of 1856, petitions started circulating asking for the division of Klamath County, because it was difficult and dangerous to reach the county seat. In fact the Crescent City Herald‘s February 23rd, 1856 issue called for Klamath to be subdivided, creating Requa County.
When the petition made its way to the legislature in 1857, in the form of a bill, several names were bandied about, but all were rejected for one reason or another. Then someone suggested, “Del Norte,” Spanish for “of the north.”
Since it seemed right, the bill passed and the new county of Del Norte was formed. At the same time, Crescent City was designated the new seat.
Eventually, though Klamath County existed in various forms for the next few years, it was finally dissolved by an act of the 1874 legislature. The public debt as well as the remaining land was divided between Humboldt and Siskiyou Counties.
Historically, it can be stated Del Norte County predated the dissolution of Klamath County by 17 years. Furthermore, California state records show no other county has been dissolved after its boundaries were officially noted by the legislature.
Finally, Klamath County still exists today. It can be found north of the California state line and east of the Klamath River in Oregon.
