Siskiyou County, California

Siskiyou County (/ˈsɪskjuː/ ^ⓘ SISK-yoo) is a county located in the northwestern portion of the U.S. state of California. As of the 2020 census, the population was 44,076. Its county seat is Yreka and its highest point is Mount Shasta. It falls within the Cascadia bioregion.

Siskiyou County is in the Shasta Cascade region along the Oregon border. Because of its outdoor recreation, Mt. Shasta, McCloud River, and Gold Rush-era history, it is an important tourist destination within the state.^{[citation needed]}

Many Native American peoples, including the Confederated Tribes of Siletz Indians, Modoc, Cayuse, Umatilla and Walla Walla and Shasta, share geography with Siskiyou County and have lived in the area for millennia prior to colonization. Siskiyou County was created on March 22, 1852, from parts of Shasta and Klamath counties, and named after the Siskiyou mountain range. Parts of the county's territory were given to Modoc County in 1855.

The county is the site of the central section of the Siskiyou Trail, which ran between California's Central Valley and the Pacific Northwest. The Siskiyou Trail followed indigenous footpaths from Native People who share the geography with Siskikyou county, and was extended by Hudson's Bay Company trappers in the 1830s. Its length was increased by "Forty-Niners" during the California gold rush.

After the discovery of an important gold strike near today's Yreka, California, in 1851, colonizers flooded the area. This was described in detail by Joaquin Miller in his semi-autobiographical novel Life Amongst the Modocs.

In the mid-1880s, the construction of the Central Pacific Railroad along the Siskiyou Trail brought the first wave of tourism. Visitors were drawn by the county's many summer resorts, and to hunt or fish. The Southern Pacific railroad, the successor to the Central Pacific, called its rail line "The Road of A Thousand Wonders."

In the early 1940s, Siskiyou County was home to the semi-serious State of Jefferson movement, which sought to create a new state from several counties of northern California and the adjoining counties of southern Oregon. The movement has seen a revival in recent years.

The origin of the word Siskiyou is not known. It may be a Chinook Jargon word for a "bob-tailed horse" (ultimately originating in Cree), or as was argued before the State Senate in 1852, from the French Six Cailloux (six stones), a name given to a ford on the Umpqua River by Michel Laframboise and his Hudson's Bay Company trappers in 1832. Others claim the Six Cailloux name was appropriated by Stephen Meek, another Hudson's Bay Company trapper who discovered Scott Valley, for a crossing on the Klamath River near Hornbrook.
